Chankasem Palace was built during the reign of King Maha Thammaraja, the 17th King of the Kingdom of Ayutthaya. During the reign of King Naresuan the Great the Palace became his permanent residence. Chankasem Palace, like the other palaces, was destroyed during the Burmese invasion. It has been renovated and reopened as a museum open to the public on Wednesdays through Sundays from 9.00 a.m. to 4.00 p.m.

In 1491, Wat Phra Si Sanphet was located inside the compound of the Grand Palace-the foundations of which are still visible-and served as the royal chapel, as Wat Phra Kaeo does in Bangkok. This Wang Lung Palace (Royal Palace) was built by King U-Thong upon the founding of the city. Used as a residential palace, it became a monastery in the reign of King Ramathibodi I. When King Borom Trai Lokanat commanded the construction of new living quarters, this residential palace was transformed into a temple,and the establishment of Wat Phra Si Sanphet. In Ayutthaya's heyday, this was the largest temple in the city. The three main chedis which have been restored contain the ashes of three Ayutthaya kings. The temple is situated at the northern end of Si Sanphet Road. The royal chapel does not have any monks and novice inhabitants. Admission fee is 20 baht.

This temple, which was built Rama V (Chulalongkorn), looks more like a Gothic Christian church than a Thai temple. Visitors can access the temple by crossing the river in a small trolley-like cable car. The crossing is free of charge. There are several nice boat trips departing from Bangkok to Bang Pa-In Palace, especially through cruise tours. The Palace is open from 9 a.m. to 3 p.m. daily with an admission fee of 50 bahts.
