History
Legend relates that Daun Penh, a wealthy widow, found a large koki tree in the river. Inside the tree she found four bronze statues of the Buddha. Lady Penh constructed a small shrine on an artificial hill made by the people living in the village to protect the sacred statues. Eventually this became a sacred site and sanctuary where people would make blessings and pray.
Then it came to the year of the snake 1437 suggests King Ponhea Yat ordered His Excellency Decho Srei to raise the mount even higher when he finished building the new Royal Palace in the new city he then named Krong Chaktomok Mongkol or simply known as Phnom Penh. The prominent stupa immediately west of the sanctuary contains the ashes of the king and his royal family.
Wat Phnom is the center of celebration during Khmer New Year, and Pchum Ben.
