The Issara Vinitchai Hall was the Audience Hall of the Palace of the Viceroy and was erected by the Viceroy in the reign of King Rama III. It is used today as a gallery for special temporary exhibition.
This building was built when the Viceroy to King Rama I, Maha Surasinghanat, built the Palace of the Viceroy. Originally used as an Audience Hall, it now houses the Thai History Gallery.
This Hall was built in 1787 to house the important Buddha image, Phra Buddhasihing. Inside the chapel, the mural paintings depict scenes from the life of the Buddha.
