Wat Preah Prom Rath is one of the most beautiful pagodas in Siem Reap. It is located on the river side, near the Old Market (Psar Chas). The monastery has many fine and colorful wall paintings and you will find many modern statues inside. Often, you will see monks in the early morning or late afternoon. They follow Buddhism courses and English classes in this pagoda.

It is not clear exactly when the pagoda was built, however, its claim to fame is the great reclining Buddha that was installed in the main temple (Preah Vihear) in 1500. There is a picturesque fable about why the Buddha is there, so if you want to find out how a boat turns into a Buddha, go and take a look. In 1915, the temple and main monastery were extended, to include an academic building (University) and a library. The expansion continued until 1945.
