Phra Prang Sam Yot

The site of a small shrine, the remains of a Khmer prang, a few stalls and lots of monkeys. The stalls sell offerings to be dedicated at the shrine, and food and drink. The monkeys eat the food, drink, offerings and anything else going. Good for a few photos. There are signs warning of purse-grabbing by the monkeys, but they appear docile if not provoked.

An annual 10-day cultural celebration held every February. It commemorates the reign of King Narai the Great (1656–1688), who transformed Lopburi into the kingdom’s second capital. Locals would wear traditional Thai attires with many activities including retro markets, light shows and other cultural activities.

The remains of Constantine Phaulkon's residence, built in the reign of King Narai the Great. Only the outer walls of the three main buildings remain, in a small grassy area.

Built in the 13th century, this is one of the town's most important monasteries; visitors can view a bas relief illustrating the Buddha's life on the central prang. No monkeys.

A viharn in the compound of a working wat, also has a small amulet market in the grounds. Previously used as a Christian chapel and a mosque, it has now been restored and features a large Buddha figure, with several smaller Lopburi-era Buddhas in wall niches.

Built in 1677 by French, Italian, and Portuguese engineers, the palace was used by King Narai to host receptions for foreign envoys. Restored in 1856 by King Mongkut, it was converted into a museum in 1924. The palace grounds consists of the remains of various buildings in an enclosed park, with the central palace serving as the Somdet Phra Narai Museum, which houses prehistoric exhibits, along with Buddha images of Dvaravati, Lopburi and Khmer styles; and King Mongkut's bedroom.
