The construction of the temple started when King Buddha Yodfa Chulaloke (Rama I) moved the capital from Thonburi to Bangkok in 1785. Unlike other temples it does not contain living quarters for monks; rather, it has only the highly decorated holy buildings, statues, and pagodas.
The main building is the central ubosoth, which houses the Emerald Buddha. There are three main doors used to enter the temple, however only the King and Queen are allowed to enter through the center door. Even though it is small in size it is the most important icon for Thai people.
