The palace was built in 1665 and 1677, when King Narai the Great decided to make Lop Buri the second capital of the Ayutthaya Kingdom. Although the buildings were designed by with the contributions of French architects, the Khmer influence was still strong. The Palace was a perfect blend of the both world, an awesome mixture of Khmer-European styles. After the death of King Narai the Great in 1688, the palace was deserted. It was not until the reign of King Rama IV during the Ratanakosin era, that the Palace was restored and renamed Narai Ratchaniwet. The Palace is located in the town center, between Ratchadamnoen Road and Pratu Chai Road. The whole complex has been turned into the Lop Buri National Museum (commonly known as King Narai National Museum). The Palace can be accessed through the Pratu Phayakkha, which is currently a town park, located off Sorasak Road. The Palace opens Wednesdays through Sundays from 7.30 a.m. to 5.30 p.m. Within the Palace lies a number of compounds containing pavilions, some built during the reign of King Narai and others constructed during the reign of King Rama IV. Structures built during the reign of King Narai the Great include:
