The imposing Swabian castle of Rocca Imperiale is on the top of the hill over which the whole residential area extends. The fortress was ordered by Frederic II of Swabia in 1221, and he ordered the construction or refurbishment of 200 castles for defensive purposes in southern Italy. The castle was built in a place of great military and strategic importance and surveillance extended to the whole of the Gulf of Taranto. The development of the residential area followed the construction of the castle, bringing in the people from a series of fortified settlements in the area. Many feudatory lords alternated in the government of the area, constantly under barbarian attack, in the following 200 years.
In 1664, the castle withstood the attack of 4000 Saracen pirates who devastated Rocca, destroying the old 13th century church in the old centre of which only the lovely Romanesque bell tower with mullioned windows and cornices remains. In 1989, the last heirs of the family owning the castle decided to donate it to the Municipality of Rocca Imperiale.

The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
