The coat of arms of
prasat noi (a small sanctuary)
underneath a tree and in the middle opening, a
conch of victory. Legend has it that when King
U-Thong in 1347 wanted to
build a new city in the district of Nong Sohn, the workers dug up a pure
white conch. This was seen as a good omen and the king ordered a sanctuary
built to house the conch.
