THUNG KHWAN (ทุ่งควัน)
Thung Khwan or "Field of Fumes" is an area north of the city of Ayutthaya bordered on the north by Thung Lum Phli, on the east
by Khlong Sra Bua and Thung Kaeo, in the south by the old Lopburi River and in the west by Thung Phukhao Thong.

Following were the temples in alphabetical order situated in this area: Wat Choeng Tha (active temple), Wat Hat Dawat (restored ruin), Wat
Kamphaeng (ruin), Wat Khao Wua (ruin), Wat Khok Phraya (restored ruin), Wat Khrut (mound), Wat Na Phra Men (active temple), Wat Phai
Lom (mound), Wat Phra Ngam (restored ruin), Wat Phrom Kalayaram (defunct), Wat Sarari (mound), Wat Sri Pho (restored ruin), Wat
Surintharacha (mound) and Wat Takrai (restored ruin).

Old villages mentioned in the "Geographical description of Ayutthaya: Documents from the Palace" [1][2]:

  • Pottery Village (บ้านม่อ) - mold small and large rice and curry pots, oven pans for making khanom khrok (small coconut hotcakes) and
    khanom bueang (filled crispy pancakes), stoves, lanterns, torches, clay dishes for cooking or burning, flower trays, wax to offer the monks at
    the beginning of the Buddhist Lent and earthen alms-bowls and spittoons. The road towards this village ran between Wat Mae Nang Plum and
    Wat Pa Khonthi and is indicated on a mid-19th century map. The exact position of the village is unknown. Phraya Boran Rachathanin noted
    that Wat Khao Wua was situated behind Ban Mo, but also wrote that the Iron market behind Ban Mo was in line with Wat Mae Nang Plum.
    From excavations in the period 2000 - 2002, we know that east of Wat Khrutharam there was a production area of large earthen pots, jars
    and massive storage vessels (see Khlong Sra Bua Kilns). We could as thus conclude that Ban Mo stretched over both banks of Khlong Sra
    Bua.

  • Tile Village (บ้านกระเบื้อง) - makes and sells “husband and wife” tiles, turtle scale tiles, hooked tiles and corrugated tiles. The exact position
    of the village is unknown. Mid Khlong Sra Bua till west of Wat Khrutharam was a production area for various kinds of earthen tiles, mainly flat
    and cylindrical tiles and other decorative parts, various kinds of antefix tiles, thick square floor tiles. In the latter area, remains of oblong updraft
    kilns were found [3].

  • Village of the Lime Pavilion (บ้านสาลาปูน) - set up furnaces to produce and sell red lime. As the name of the village indicates, it should have
    been located in the vicinity of Wat Sala Pun and Wat Phrom Niwat. Phraya Boran Rachathanin also mentions that there was a market in this
    area. [4]

  • Khao Luang Village (บ้านเขาหลวง) - the Chinese community set up a factory for boil liquor (liquor distillery) for sale. The exact position of
    the village is unknown.

Ref [1] mentions the existence of five villages but only mentions four. The document also gives no indication of the proximity of a monastery which
could be used as a reference point.

Wat Sala Pun was likely the religious center of Ban Sala Pun (Village of the Lime Pavilion); hence Thung Khwan could have been stretched out
towards Hua Laem.
