Now a small city in southern Thailand, Sukhothai was once the seat of an ancient Siamese culture. The Sukhothai National Historic Park has been named a UNESCO World Heritage Site, and is dedicated to preserving the area's many temples, palaces and monuments, which date back to the 13th century. The old city covers roughly 27 square miles (70 sq km) and is divided into three zones, each of which charge separate admission. There are bicycle rentals available, and there is a tour by electric tram. New Sukhothai, 7.5 miles (12km) from the historic park, features a fresh market with great local food, and a few shops and restaurants.
