Also known as Wat Klang, Located on Sai Buri Road, this large temple is perhaps the most important Buddhist temple in Songkhla. It is said that Yai Si Chan, a Songkhla millionaire donated a large sum of money to construct this more than 400 years old temple. Later on Wat Liap was built to the north and Wat Pho to the south. The local residents then changed the name of the temple from Wat Yai Si Chan to Wat Khlang or Wat Matchimawat. This temple also has the Phattharasin Museum that houses various artifacts collected from Songkhla, Sathing Phra, Ranot, and other places.
