The monastic structures in Wat Phra Sri Sanphet were basically straight aligned on an
east-west axis. The main entity was formed by the prasat, the three chedis with their
mandapas, and the Royal vihara or chapel presiding over all structures.

The three chedis, being the core of the temple, rested on a high platform with the later
built mandapas (square structures with a spire) situated at the eastern side of each chedi.
The elevated platform was surrounded by a walled gallery, running from the westside of
the Royal chapel towards the eastern portico of the prasat, a cruciform structure.

On both sides of the Royal chapel were minor vihara aligned north to south. On the north
side stood the Vihara Phra Lokanat (the Vihara of the Protector of the World). On its
south side stood the Vihara Phra Palelai (the Vihara of the Parileyyaka Buddha). A
parallel north-south alignment was formed by the ordination hall (Vihara Phra Palelai) and
by the Sala Chom Thong (east of Vihara Phra Lokanat). The bell tower stood nearly in
the same axis, but in front of the Royal chapel.

We will define some of these structures by following more or less the timeline of
construction of the monastery.

The first chedi on the eastern side was constructed by King Ramathibodi II (r. 1491-1529) in 1492 A.D. to enshrine the ashes of his father, King
Borommatrailokanat (r. 1448-1463).

On the inner wall of the crypt is a mural painting on lead sheets believed to be from the period of the construction of the chedi, depicting Buddhist monks
walking while holding lotus flowers in their clasped hands. Fine Arts Department (FAD) found during excavations in 1932 in this chedi a stupika consisting of
eight smaller stupas, one enclosing the other likely to have contained the relics of the deceased king. The outer stupa crumbled. The other seven are on
display at the
Chao Sam Phraya Museum.
The second chedi - the present middle one - was built at the same time of the first, to enshrine the ashes of his elder brother, King Borommaracha III (r.
1463 -1488). The two chedis were lined up on an east-west oriented axis. Eight years later, a Royal vihara was constructed in the same alignment of the

The third and western chedi was built 40 years later by King Boromracha IV (r. 1529-1533) to enshrine the remains of his father, King Ramathibodi II.

All three bell-shaped chedis are identical and were constructed on a rectangular platform. The chedis are built in the Sukhothai style - derived from the
Srivijayan stupa, characterized by superimposed pedestals - only differing from the latter that they have four outward-jutting porches in the four cardinal
directions, decorated with a small – identical to the main chedi – stupika on the roof of the porch - a feature probably derived from the Khmer architecture.
The porches have a niche in which a standing Buddha image was placed on three sides. The porch on the east side gave access to the garbhagrha, a small
sacred chamber in the interior of the chedi in which consecrated objects, in this case the King’s ashes, were contained.

A typical feature of the Ayutthaya-styled chedi is the presence of vertical pillars (Th: Sao han) decorating the shaft and supporting the spire above the
harmika. The vertical pillars break the monotony of the repetitive horizontal rings of the pinnacle. It is a characteristic differing from the Sukhothai-styled
stupa and this design was probably for the first time here initiated.

The chedis of Wat Sri Sanphet demonstrate thus the beginning of a new architectural style, influenced by the Sukhothai art, at the same time abandoning the
prang-styled construction of the Early Ayutthaya Period.
Vihara Luang or Royal Chapel

The Royal chapel was built in 1499 in the reign of King Ramathibodi II, prior of course
the construction of the third chedi, which would contain the latter’s ashes. The initial
vihara had eleven sections of approximately 4.6 meter length, totaling a length of 50
meters. The construction stood isolated from the two chedis already built. The building
had a front and back porch, with two entries each.

The walls had no windows, but vertical slit openings, bringing ventilation and providing
at the same time a diffused light into the inside. Apparently even the back wall had
these openings. The gabled roof was supported by two rows of pillars in the interior of
the chapel and two rows of pillars at the exterior, forming as thus a colonnade at each
side of the building, an architectural style from the Middle Ayutthaya Period. Also here
is Sukhothai art influence visible as some columns still bear capitals in the form of a
stylized lotus. As the gables and tiled roofs were wooden structures, it is clear that the
chapel must have undergone many restorations

When visiting the structure, a pedestal inside the chapel, where upon once a golden
Buddha images stood, can still be seen; including some stucco displaying parts of a lion’
s foot. The pedestal in the back has been reduced to a pile of rubble.

The chapel has undergone two major restorations. During the reign of King Prasat
Thong (r. 1629-1656) the building was extended at the back, in a way that the 1.6 m
wide stairs of the back porch penetrated and entered the newly built gallery. The
second renovation took place during the reign of King Borommakot (r. 1733-1758).
The walls of the front porch were dismantled and six more pillars were erected to
support an additional roof section.
The gallery

A gallery, surrounding the three main chedis and incorporating partly the back porch of
the Royal Chapel, was built during the first major renovation in the reign of King Prasat
Thong. Buddha images in the Subduing Mara posture were installed inside the gallery,
facing outwards (back to the chedis); a bit unusual since Buddha images in a gallery face
usually inward. On the four corners of the gallery, small pagodas - named "Phra Agghiya
chedi" - were constructed in an identical style as the principal chedi.

The prasat

The prasat (2) at the west side of the temple was a building which served religious
purposes, being a shrine for venerated objects or memorial hall. The ground-plan
was a Greek cross, while the roof-structure ended in a slender prang. The prasat
is a direct stylistic descendant of the Khmer temple. A square sanctuary with a
domed sikhara (tower) and four porch-like antechambers that project from the
main building, giving the whole temple a multileveled contour. The building was
added during the reign of King Narai.

The ubosot

The ubosot or ordination hall was located on the southeastern side of Royal
Chapel and east of Vihara Palelai. The hall was rectangular and measured 33
meters by 15 meters. The structure was made of brick and initially open sided.
The building was restored a number of times at par with the other monastic
structures in situ. During probably the first renovation in the reign of King Prasat
Thong walls were erected to close the structure, while the pedestal for the Buddha
image inside the ubosot was extended to seal off the back portico. As most
monastic structures the roof structure was made of wood and covered with
unglazed terra-cotta tiles. The boundary stones (Th: bai sema), made of slate are
believed to be the originals as they bear the characteristics of the Middle
Ayutthaya period (1488 to 1629 AD).

The door panels of the ubosot survived the Burmese war of 1767 and are
displayed at the
Chao Sam Phraya Museum. The panels are made of wood and
measure 1.10 meters by 2.40 meters. They were beautifully carved in high-relief
depicting Dvarapala (3) and are testimony of the exquisite Ayutthayan art.

Sala Kanparian

The Sala Kanparian was a building where the monks studied the Buddhist
scriptures. Wat Phra Sri Sanphet had such a building, named the Jom Thong
Pavilion, though there were no monks residing in the temple. This pavilion was
situated east of vihara Phra Lokanat and contained a Buddha in sitting posture
called Phra Jom Thong. This location is referred to in the Royal Chronicles of
Ayutthaya as being the place where King Song Tham was listening to the monks
explicating books at the start of a rebellion of some Japanese traders in 1611. The
latter were already present at the palace eager to find the King. Eight monks of
the Monastery of the Pradu Three (the present
Wat Pradu Song Tham) escorted
the King away in front of the baffled Japanese, who undertook no action against
him. Jom Thong Pavilion also called Phra Thi Nang Jom Thong was built on a
rectangular base. It had three porticos, one in front and the other two at the sides.
Inside the building there were two rows of pillars supporting the beams with seven
partitions (space between the pillars). The roof was tiered and gabled with rows
of pillars supporting the eaves similar to Sukhothai architecture.

Dutch merchant Jeremias Van Vliet wrote in his work 'Description of the
Kingdom of Siam' (1638) that the original books of King U-Thong or
Ramathibodi I, first King of Ayutthaya, were kept at Wat Phra Sri Sanphet. These
manuscripts were probably kept at the Jom Thong pavilion. [3]

"All these laws and foundations of religion he has written himself and has
bequeathed them to his subjects. These original books, together with many
others which were added in later years, are still kept in Judia in the king’s
finest temple, now called Wat Siserpudt,  and are held in great honor."

The chapels

Twenty-six chapels consisting each of a vihara and a bell-shaped chedi in Ayutthayan
style, were built along the outer wall, within the monastery compound. The ashes of the
members of the royal family were kept inside these chedis. Traces of lime stucco still can
be found on the walls of a vihara on the south side of the temple.

The bell tower

The bell tower has undergone three restorations. A new structure was built over the
original gong and drum tower, made with brick columns and a wooden floor. The last
restorations had a five-tiered rooftop and four porticos.

The inner wall

Although important monastic structures, such as an ubosot or royal vihara were
traditionally surrounded by a low inner wall - separating the sacred world from the
secular hustle and bustle outside - no such wall could be found on the premises of Wat
Phra Sri Sanphet.

The Royal Chronicles although mention the existence of an inner wall during King Prasat
Thong’s reign. The records mention the king visiting the Royal chapel and encountering a
son of the King Songtham, the young Prince Athittayawong sitting on the wall. The prince
did not descend the wall on approach of the king to pay his respects and was straight
punished to become a commoner to live near
Wat Tha Sai.

"His Majesty came on a tour in front of the large holy preaching hall and, glancing
with His holy eyes, saw Holy Athittayawong, the royal son of Holy-Lord Song Tham
who had been removed from the royal wealth, ascend and sit dangling his feet
upon the back of the
crystal wall. Indicating him with His holy hand the King said,
Athittayawong is rash in failing to descend from the crystal wall in order to be
lower than the King. Indicating him with His holy hand the King said,
Athittayawong is rash in failing to descend from the crystal wall in order to be
lower than the King. Strip Holy Athittayawong of his rank and send someone to
build two houses with bamboo posts and two rooms beside the Monastery of Sand
Landing for Athittayawong to have two people live with him - just enough to stay
to dip up water and cook rice
The outer wall and bastions

The Phra Sri Sanphet monastery is surrounded on all sides with a high thick brick wall
with embattlements on the top. There were four gates built in the cardinal directions.
The southern gate giving access to the front court of Wihan Mongkhon Bophit, was
called "Pratu Bowon Nimit" or "Gate of the Excellent Omen". Pratu Chong Kut, the
western gate, gave access to the Tamnak Suan Kratai or the Rabbit Garden Royal
Pavilion. The western gate gave access to the inner court of Phra Thi Nang Jakkrawan
Phaichayon (throne hall), while the northern gate was the entry to the palace. The entry
was a long covered corridor (Th: chanuan) running through the palace area from Tha
Wasukri in the north until Wat Phra Sri Sanphet in the south, offering discretion and
shade. The monastery had two forts. A main fort called Pom Sala Phra Wihan
Mongkhon Bophit was a semi-large bastion protecting the southern part of the palace
area. From the protruded bastion, soldiers could control the whole southern wall. A
second smaller bastion called Pom Mum Wat Phra Sri Sanphet stood on the
southwestern corner of the monastery's premises.

(1) A mondop is a building with a square structure and a stepped pyramidal roof, built
to house objects of special veneration - a Buddha image or footprint.
(2) Skt: Prasada or castle was a residence of a king or god. The term is generally used
in the sense of sanctuary tower (Khmer).
(3) "Guardian of the Gate" also known as the protector of shrines; often standing and
holding a club, frequently at the entrance to a temple.

The mandapas

There were four mandapas (Th: mondop) (1) constructed in Wat Phra Sri Sanphet. The
first three were built on the square base between the three main chedis. These mandapas
had a spired top. Scholars assume that the mandapas may have been built in the reign of
King Prasat Thong.

A fourth mondop was constructed close to the northern wall of the temple. The structure
of this mondop deviated from the classic one, as it was a cruciform structure topped in
the middle with a small prang; a bit a mixture of a prasat and a classic mandapa. The
doors and windows were in gothic style, bearing French influence. Scholars assume it
was built during the reign of King Narai and housed the remains of his father King Prasat
(Remnants of the gallery)

Questioning the construction date of Ayutthaya's landmark

The dating of the Ayutthaya monuments is commonly based on the dates mentioned in the Royal Chronicles of Ayutthaya written in the Early
Ratanakosin period. Piriya Krairiksh in his document "A Revised Dating of Ayudhya Architecture" brings to the attention that the possibility
might exist that the monuments we see today may have been built at a later period. [4]

Piriya Krairiksh arguments that there is nowhere written in the old documents that the ashes of King Borommatrailokanat and King
Borommaracha III were enshrined each in a stupa (hence enshrined in two stupas), while there is also no indication of the location of the stupa
nor a mentioning of a specific temple. The oil painting of "Iudea" of c. 1659 in the Rijksmuseum, Amsterdam and the watercolour painting from
Johannes Vingboons' atlas of 1665 does not depict a stupa at the rear of Wihan Luang, and therefore he believes the timing of the construction
of the three stupa should be revised. (1)

Referring to the "Plan of the Royal Palace of Siam" published by Engelbert Kaempfer, he concludes that the chedis seen on the plan are
probably built between 1665 and 1688 during the reign of King Narai, since all of these additional structures are missing on Vingboons' atlas of
1665. He also remarks that the chedi on Kaempfer's plan are of the multi-storeyed prasat type and not of the present bell-shaped Sinhalese

Krairiksh writes that if we compare the present architectural lay-out of Wat Phra Sri Sanphet with Kaempfer's plan of 1690, nothing of the
structures shown in the latter plan remains. The Royal Chronicles of Ayutthaya mention that King Borommakot ordered the complete
renovation of Wat Phra Sri Sanphet in 1742, which makes Krairiksh assume that the earlier structures had been demolished and replaced by
three Sinhalese-type stupas alternated with three mandapa, laid out along an east-west axis following a symmetrically designed master plan from
the early 1740s.

I agree with Krairiksh in questioning the date of construction of the three bell-styled chedi of Wat Phra Sri Sanphet set at the end of the 15th
century following the chronicles. No Siamese construction from the past survived a long time in the torrid zone in its original form; add to this
that the Siamese were far from industrial to maintain their temples and let them mostly dilapidate overtime, to finally pull them to the ground and
rebuilt them thereafter. The chronicles mention that the complete renovation of Wat Phra Sri Sanphet by King Borommakot (r. 1733 - 1758) in
1742 took more than one or two years depending the versions. It is as thus plausible that older structures were completely torn down and
replaced by new ones (in another style), as we have the same case with
Chedi Phukhao Thong. King Borommakot had the chedi rebuilt in
1744 on a square pedestal with indented corners and niches on the four sides, while the cylindrical dome was changed to one of a square plan
with rabbeted angles. The three bell-styled chedi of Wat Phra Sri Sanphet could as thus only date back to the mid-18th century and should as
thus no be taken as a main example of the second architectural sub-period (1488 to 1629 AD), but rather as part of the fourth sub-period
(1732 - 1767 AD).


(1) Krairiksh uses a wrong element from the oil painting "Iudea", the structure being Wat Maha That instead of Wat Phra Sri Sanphet.
