Petchaburi is home to Maruekkhathayawan Palace, one of the oldest royal palaces in Thailand. The area’s royal connections are even more apparent at Phra Nakhon Kriri Historical Park, a palace built by Thailand’s King Mongkut. A further royal palace can be seen at Phraram Ratchaniwet. Petchburi is a fascinating province to visit, and exploring aspects of its history and culture is a very rewarding thing to do.
