According to an old account, a fortress known as Waindawula Fortress has stood in the land of Siompu since ancient times and remains standing to this day. The fortress, which once served as a defensive stronghold in Siompu, was not merely an ordinary protective wall. In the Muna language, the term Waindawula means “old village.” Within the fortress stand six sturdy wooden supporting posts and three elegant gates, constructed to resemble the grandeur of the pillars of the Buton Palace.
