This is a King's pavillion in front of the Royal Palace, on the riverfront embankment. It houses king, royal family and government officals during the Water Festival in November every year to watch the boat racing in the Tonle Sap River. The earlier's construction during the time of King Sisowath and King Monivong was a floating house moored on the river opposite the Royal Palace, and was later disassembled and replaced with this new pavillion.
