Wat Phrom Kalayaram, sometimes mentioned as Wat Phra Kalayaram, (Th: Kalaya =
older sister) was located off the city island in the northern area in Khlong Sra Bua
sub-district. The temple was situated on the west bank of
Khlong Sra Bua in an area
Thung Khwan. Wat Sri Pho stood in the south, Wat Phra Ngam in the west and
Wat Bailo on the opposite side of the canal.

Not much is known of this temple. The temple site was occupied by the Burmese army
in the last Burmese-Ayutthaya war of 1766-1767. The story goes that many Burmese
soldiers were killed on this site due to a heavy large gun fire from the city. Apparently the
ordination hall (Th: ubosot) was not destroyed. The adjacent Wat Sri Pho and Wat
Phrom Kalayaram were fused together in 1942. A new ubosot was built on the ruins of
the old ubosot of Wat Phra Kalayaram and the whole complex received the name Wat
Mai Sri Pho (The word "Mai" meaning "new").

Historical data about the monastery and its construction are unknown.

The site is mentioned on
Phraya Boran Rachathanin's map drafted in 1926 and was
situated in Geo Coord: 14° 22' 16.47" N, 100° 33' 27.55" E.
