It is a temple located at the foot of Khao Khuha Sawan near the city market. This is one of the ancient monuments of Phatthalung.
Assumably, it was built in around the 8th-l0th centuries. Inside the cave, a giant reclining Buddha image, pagoda, and other Buddha images are found together with some earthen votive tablets of the Srivijaya period.
Inscriptions of royal initials belonging to King Rama V and Their Majesties the King and Queen appear in front of the cave. Furthermore, stucco arts in Tham Nang Khlot depict folklore.
