Located in the valley of the Yom River, Sukhothai (meaning "Dawn of Happiness") is a province in northern Thailand which verges on the central regions. It is around 427 kilometres north of Bangkok and covers around 6,600 square kilometres. The province was founded in the 13th century and was the first independent Thai Kingdom - the Sukhothai kingdom. It is most famous for the historic city of Sukhothai, the kingdom's capital. The province's temples and monuments have been restored to their former glory and Sukhothai Historical Park - a place with countless sites of historical interest - made into a UNESCO World Heritage Site. Other places of interest include Ramkhamhaeng National Museum, Ramkhamhaeng National Park, Sri Satchanalai National Park and The Royal Palace and Wat Mahathat.
