The Roman Catholic Cathedral was built in the 15th and 16th Centuries. The cathedral suffered severe damage during WW II. The roof collapsed and one of the towers suffered severe damage. A major restoration effort began after the war and was carried out in several stages, the last of which came to an end in 1994 (Source: Wikipedia).
