The Norman castle is the most important monumental complex of Tricarico to which the most salient monuments of its political and religious history have been connected since the Middle Ages. Probably built in the IX – X century as a fortified fortress and endowed with a robust and emblematic 27-meter tower, at the highest point of the town, it was strengthened in the Norman-Swabian period, in defense of the Kastron of Tricarico.
The tower carried out its military function until the ‘600, while the castle became, in 1333, the seat of a prestigious monastery of cloistered nuns, founded by Sveva, countess of Tricarico and widow of Tommaso Sanseverino.
The Norman tower was declared a national monument in 1931.
