It is a huge Catholic church on the island of Capri, originally the cathedral of the Diocese of Capri in the period 987-1560, and it is a church dedicated to Saint Costanzo. It is distinguished by its simple architecture built in the Arab style, where the church has a modest white facade that dates back to the late nineteenth and early twentieth centuries, when the balcony was demolished to provide stone for the construction of the priest's house. The church building consists of four small pointed domes supported by four arches and twelve columns.
