Wat Sam Phraya is a Thai royal temple of the third class, located in Wat Sam Phraya Sub-district, Phra Nakhon District, Bangkok. Formerly called Wat Sak or Wat Bang Khun Phrom, it was presumably built in the Ayutthaya period. It was restored and given its present name in the Bangkok era.
Bangkok, officially known in Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand.
The majority (93 percent) of the city's population is Buddhist.
Rama I (reigned 1782–1809) of the Chakri Dynasty (which remains the current royal family of Thailand) founded the Rattanakosin Kingdom.
Under Rama I, new temples were constructed at the new capital of Rattanakosin (modern Bangkok), such as the royal Wat, Wat .
