Szigetvár Castle became known throughout Europe in 1566. At this time the castle became a symbol of the struggle against the Turks when Miklós Zrínyi, heroic captain of the castle, fought to the bitter end with his Hungarian and Croatian troops. Following their victory the Turks rebuilt the ruined three-part castle into the single castle of today, with the castle built of bricks and the bastions of stone. The ruined buildings were replaced by new ones and a mosque dedicated to the memory of Sulejman was built in the middle. The town became a prominent centre of the occupation, although its original structure was not changed. Following many destructions and much rebuilding the castle has retained the structure and character of the 16th Century motte castle.
The former bog has disappeared leaving a park with rich vegetation.

In the 1930’s Count Andrássy joined the mosque onto the summer residence in which the castle-history Miklós Zrínyi Museum, founded in 1966, is partly housed.

During excavations of the inner courtyard the foundations of the mediaeval tower were found, as well as the well and remains of the square shaped knight’s castle, with the moat surrounding it. The area of the inner castle was discovered and the moat ditches, scene of the fatal dash of Miklós Zrínyi and his men. Here the equestrian sculpture of Zrínyi by József Somogyi was placed.
Turkish memorials in the town include the Turkish House (3 Bástya Street) and the Turkish-Hungarian Friendship Park beside the road to Kaposvár.
