The Sanctuary of Truth is an unfinished museum in Pattaya, Thailand designed by Thai businessman Lek Viriyaphan.[2] The museum structure is a hybrid of a temple and a castle that is themed on the Ayutthaya Kingdom and of Buddhist and Hindu beliefs. The building is constructed entirely of wood, specifically Mai Deang, Mai Takien, Mai Panchaat, and Teak. It contains only wood-carved idols and sculptures. Construction began in 1981 and is still in construction, though visitors are permitted inside with hard hats. Located on 13 hectares of land, the temple houses an internal space of 2,115 m2, with the tallest spire reaching 30 m (98 ft)
