The area quickly became a trade center, which is confirmed by the title of the Shahbandar (port master) of that period, I Daeng ri Mangallekana.
In the 1630s, kings and nobles established their residence in Somba Opu, staying in a house built on thick pillars.
According to Dutch maps drawn on a model from the 1630s, a number of detached houses were located in the rear (east) and northern side of the fort.
They were grouped around the royal complex in the southwest side of Somba Opu, which consisted of two enormous wooden palaces, storehouses, and a mosque.
[2] Destruction of Somba Opu began with the signing of the Bungaya Treaty in 1667 between the Sultanate and the Dutch, and the subsequent war in 1669.
[2] Attack of the fort began with Cornelis Speelman, admiral of the VOC, gathering forces which consisted of 2,000 Bugis soldier, the archrival of Gowa, plus additional 572 men from Ternate, Tidore, Bacan, Butung, and Pampanga (from northern Luzon in the Philippines), 83 Dutch soldiers and 11 Dutch sailors.
Three small Dutch ships and a sloop were set along the Garassi (now the Jeneberang) to attack Somba Opu from the south.
The fort defenders reacted by sending 25 warriors to block the attackers from breaching in, while others began to erect wooden stakes to close the hole.
On 22 June, after a 6 days of continuous rain, Arung Palakka decided to lead his Bugis, Bacan and Ambon soldiers to enter the breach in the wall.
Despite the rain, the Bugis managed to set up a fire to force the Makassar soldiers to retreat from the eastern and western bastions of the citadel.
As the Dutch-Bugis army advanced from the west, a report came mentioning that the Makassar forces had fled and abandoned Somba Opu.
[6] As soon as Somba Opu fell, 8,000 Bugis began to seize the booty, among the most sought item were porcelain and copperwork.
[1] By the time Speelman and Arung Palakka arrived at the Sultan's residence in Somba Opu, everything had already been stripped bare.
[1] Bricks of the walls of Somba Opu were reused for Dutch buildings or local population's wells and house foundations.
