Thailand: The Bang Pa-In Palace grounds with the Aisawan Thiphya-Art (Divine Seat of Personal Freedom) pavilion in the middle of the lake, Bang Pa-In, Ayutthaya Province. The palace, also known as the Summer Palace, is a palace complex formerly used by the Thai kings. It lies beside the Chao Phraya River. King Prasat Thong constructed the original complex in 1632, but it fell into disuse and became overgrown in the late 18th and early 19th centuries. King Mongkut restored the site in the mid-19th century. Most of the present buildings were constructed between 1872 and 1889 by King Chulalongkorn.
