The old Thai capital of Ayutthaya, a UNESCO World Heritage Site, is one of the most impressive ruined cities in Asia, and a must-see for history buffs visiting Thailand. The Menam, Lopburi, and Pasak rivers ring the island of ruins. Wandering through this once-thriving place will make you feel you’ve stepped back through time. Allow at least two days to see all of Ayutthaya’s attractions, and more if you don’t want to feel rushed. This place is steeped in history and you’ll want to get the full experience while you’re here. Ayutthaya Historical Park is open 8:30 am-4:30 pm daily.
1 Wat Phra Si Sanphet
Wat Phra Si Sanphet is the loveliest but also the most historically important temple in old Ayutthaya. Its three large chedis and numerous smaller ones make this wat one of the most impressive sights in the ruined city.
