When Field Marshall Plaek Pibulsongkram was Prime Minister, the government acclaimed the Regulations on the Administration of the Phetchabun Municipality and established the Ministry of Treasury at Tham Ruesi Sombat. It was used as a place to collect the treasures of the country during that period. Today the buildings cannot be seen except the cave where some traces of construction can be noticed. To get to The Tham Ruesi Sombat cave from Phetchabun, take Highway No. 21, there will be a direction sign to the entrance of the cave at the junction opposite the entrance to the Phetchabun Airport, and go further for 6.5km.
