Yaksha is the name of a broad class of nature-spirits, usually benevolent, who are caretakers of the natural treasures hidden in the earth and tree roots. They appear in Hindu, Jain and Buddhist mythology. Wat Matchimawat was built in the 17th century CE and is one of Songkhla's most important temples. The name Songkhla is actually the Thai corruption of Singgora; its original name means 'the city of lions' in Malay. This refers to a lion-shaped mountain near the city of Songkhla. Songkhla was the seat of an old Malay Kingdom with heavy Srivijayan influence. In ancient times (200 AD - 1400 AD), Songkhla formed the northern extremity of the Malay Kingdom of Langkasuka. The city-state then became a tributary of Nakhon Si Thammarat, suffering damage during several attempts to gain independence.
