The town's fortress was the setting of the Battle of Szigetvár in 1566. It was a sanjak centre at first in Budin Province (1566–1601), later in Kanije Province (1601–1689).
There was already a bum in the marshland back in the Celtic and Roman times. The Castle of today was built on an artificial island - created by filling up the swampy area and driving the stream into a canal - in the 15th century. If you walk along the top of its external walls, 4 m thick at some places, you can get great views of the town. The bridge over the inner moat stands at the place where Nikola Šubić Zrinski and his soldiers broke out of the inner castle.

Two years after the siege, the mosque of Ali Pasha was built up, later - in 1788 - to be transformed into a Christian church: the Roman Catholic parish church.

The Turkish House of red raw brick walls and interlaced steel window grills in Bástya Street was originally destined to be a caravanserai. The two holy-water basins of the Franciscan Church were made of Turkish washbasins. The carved main altar of the Baroque Church is another sight to see.
In 1966, on the 400th anniversary of the siege, Szigetvár regained its old rank of a chartered ancient city. Development began to gather speed. Today it has a
