The Cathedral of Cosenza sits in the historic heart of the old town, a Romanesque-Gothic building consecrated in 1222 and substantially modified over the following centuries. The façade blends Romanesque solidity with Gothic pointed arches in a way typical of southern Italian medieval architecture.
Inside, the most remarkable object is the Stauroteca — a Byzantine reliquary cross donated to the cathedral by Emperor Frederick II at its consecration. The Stauroteca is a 12th-century piece of Byzantine goldsmithing, elaborately jewelled and enamelled, and it alone makes the cathedral worth entering. The building also contains the tomb of Isabella of Aragon, Queen of France, who died at Cosenza in 1271 after falling from her horse.
