Sukhothai, meaning the "Dawn of Happiness" was the first free Thai capital founded in 1238. The years that this kingdom thrived are viewed as the Golden Age of Thai civilization and the religious art and architecture are considered to be the most classic of Thai styles. Sukhothai features plenty of ruins spread over 27 square miles, including the largest wat in the city, Mahathat. Built in the 13th century, it is surrounded by brick walls and a moat. There is also a much-photographed 11-metre seated Buddha in Wat Si Chum. Before venturing to other wats, make a stop at the museum where you can view a great sampling of Sukhothai artifacts.
