Cathedral of the Assumption in Koper

The Cathedral of the Assumption of the Blessed Virgin Mary also called Koper Cathedral is the Catholic cathedral of the Diocese of Koper, in the city of Koper, Slovenia.The church was built in the second half of the twelfth century in Romanesque style, with three naves, each ending with an apse. Until 1392 the church underwent changes and additions, which also led to a change of style: the western facade is clearly Gothic. After an earthquake in 1460, the facade was redesigned in 1488, with the addition of Renaissance elements.
