Wat Yannawa is an old Buddhist temple (wat) dating back to the Ayutthaya period, located in the Sathon district of Bangkok on Charoen Krung Road, Bangkok, Thailand. It has a unique junk shaped chedi and viharn built by King Rama III. The idea behind the construction was that Chinese junk was quickly disappearing and the pagoda should show present descendants what it looked like. The temple was originally known as Wat Khok Khwai during Ayutthaya era and Wat Khok Krabue (วัดคอกกระบือ) during Thonburi and early Bangkok era before the construction of the chedi.
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 .
