Tricarico Cathedral is a Roman Catholic cathedral church in the city of Tricarico. Robert Guiscard erected the present building in the Romanesque style in the 11th century using a gift from his nephew Robert, Count of Montescaglioso. Louis I, Duke of Anjou was crowned there in 1383. The church has been remodelled and enlarged several times over the centuries, by Bishops Pier Luigi Carafa senior in 1638, Pier Luigi Carafa junior after the plague of 1657 and Antonio del Plato between 1774 and 1777. The work carried out by the latter bishop gave the cathedral its present appearance.
The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
