THUNG KAEO (ทุ่งแก้ว)
Thung Kaeo or "field of crystal" was an area north of the city of Ayutthaya bordered on the west and north
by
Khlong Sra Bua; on the east by Khlong Hua Ro and in the south by Khlong Mueang. The area was cut through by at least two
canals running parallel with Khlong Sra Bua, being the
Pha Lai canal and  the Ban Pla Mo canal. There existed also a  side canal
from the
Lopburi River opposite Wat Sam Vihan, called Khlong Wat Phrao. The whole area is low land and prone to yearly
flooding.
