King Narai's Palace

King Narai's Palace (Phra Narai Ratchaniwet) is a 17th-century royal palace in Tha Hin, Mueang Lopburi, Lopburi town. Built in 1666 by King Narai the Great as a second capital of the Ayutthaya Kingdom, it blends Thai, Khmer and European architectural styles. Now housing the Lopburi Museum (King Narai National Museum), it displays archaeological artifacts and Lopburi history within restored halls, courtyards and fortified walls.

Visitors can explore a walled palace compound with restored halls, courtyards, reception buildings and gardens. The main structures include Dusit Sawan Thanya Mahaprasat Hall, Chanthara Phisan Hall and Phiman Mongkut Pavilion, now used as museum exhibition buildings. Inside are archaeological finds, Buddha images, ceramics and historical exhibits related to Lopburi and the Ayutthaya period. The grounds feature European-influenced arches, lotus ponds and open areas for walking and photography.

Built in 1666 by King Narai the Great of Ayutthaya as a second capital and residence for conducting foreign diplomacy. Designed with assistance from French and Italian architects, it served as the centre for relations with France, the Vatican and Persia. After King Narai's death in 1688 the palace was abandoned until restored by King Mongkut (Rama IV) in the 19th century, who added Phiman Mongkut Pavilion. It now functions as the King Narai National Museum under the Fine Arts Department.

Represents the peak of Ayutthaya's international engagement and Lopburi's role as a second capital. The architecture illustrates cultural exchange between Thai, Khmer and European traditions. The site is central to Lopburi's identity and hosts the annual King Narai Festival, where history and local traditions are presented through costumed reenactments and cultural performances.
