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.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
