Wat Kalayanamitr Varamahavihara is a Buddhist temple (wat) in Bangkok, Thailand. The temple is located in Wat Kanlaya sub-district, on the Thonburi bank of the Chao Phraya River. The temple was established in 1825 by Chaophraya Nikonbodin, a wealthy Thai Chinese trader, who donated the temple to Rama III. Chaophraya Nikonbodin was an ancestor of the Kalayanamitr family, whose descendants include Saprang Kalayanamitr. A poem inscribed in the temple reads:
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 .
