The Phraya Nakhon cave is best known for the Kuha Karuhas pavilion in the main chamber. The pavilion was built at the end of the 19th century for the visit of King Chulalongkorn the Great (Rama V). Later, King Prajadhipok (Rama VII) and the present King of Thailand, King Bhumibol Adulyadej (Rama IX) also visited the cave.
