Chicken Dung Prision
The notorious Khuk Khi Kai, at Laem Sing, was built to hold Thais who were against the French occupation of Chanthaburi in 1893. A 7-metre high, square-shaped prison, it was built with bricks with each side measuring 4.40 metres. The porous roof is said to have been used as chicken coop through which the birds dropped their excrements.
