The Buton Palace Fortress received awards from the Indonesian World Records Museum (MURI) and the Guinness Book Record, which was issued in September 2006 as the largest castle in the world with an area of about 23,375 hectares.

From the edge of the fort, which still stands firmly, you can enjoy the view of the city of Bau-Bau and back and forth ships in the Strait of Buton clearly from a height, a sight that is quite frightening.

In addition, in the fort area, various historical relics of the Sultanate of Buton can be found.

This cannon is a former weapon of the Sultanate of Buton, a relic of the Portuguese and Dutch, which can be found in almost all fortifications in the city of Bau-Bau.

The word baluara is derived from the Portuguese language baluer which means bastion.

Baluara was built before the castle fort was founded in 1613 during the reign of La Elangi / Dayanu Ikhsanuddin (the fourth buton sultan) together with the construction of 'godo' (warehouse).
