The temple of Wat Peapahd is just north of the main market of Psar Nat. The temple and school has a rather nice main chapel, along with another large hall that has some rather nice Khmer details along with European lines. There are also several funerary reliquaries around the edges of the temple grounds, some of which are quite large and elaborate. The temple is good for a stroll if you're also wandering around the market, but it's probably not worth a special trip.
