Wat Maha Samanaram Ratchaworawihan

Wat Maha Samanaram, also known as Wat Khao Wang, is a second-class royal temple (Ratchaworawihan) of the Thammayut order on the eastern slope of Phra Nakhon Khiri. Formerly called Wat Samon, it is thought to date from the Ayutthaya period.

When King Mongkut (Rama IV) built the Phra Nakhon Khiri palace, the monks moved elsewhere and the temple was left deserted. The king then had it restored under the supervision of Chao Phraya Si Suriyawong (Chuang Bunnag).

The ordination hall holds tempera murals by Khrua In Khong and four other painters, showing pilgrimages to sacred sites such as the Buddha's Footprint, Phra Pathom Chedi and the great relic stupa of Nakhon Si Thammarat. Painted in Western-style perspective blended with Thai style, they are Khrua In Khong's only work in Phetchaburi province.

Behind the temple is Phutthakosa Cave, with a reclining Buddha about 3 wa (around 6 m) long.
