The National Museum of King Narai is home to exhibits featuring artifacts ranging from prehistoric times to the Rattanakosin era, primarily sourced from Lopburi and its surrounding areas. The museum also showcases various items that reflect the lifestyle of the people living in the central river basin. King Narai the Great commissioned the construction of the museum in 1666 (B.E. 2209) on an area of 41 rai in the city of Lopburi, intended as a royal residence, a hunting ground, a place of governance, and to host dignitaries and guests.
