The Urban Tower in Košice, Slovakia is a renaissance prismatic campanile with a pyramidal roof. It was erected in the 16th century. The St. Urban Bell, a church bell installed in the tower, has been dedicated to Saint Urban, the patron of vine-dressers. The bell was cast in a mould by the bell-founder Franciscus Illenfeld of Olomouc in 1557. Its weight is seven tonnes. In 1775 the pyramidal roof was constructed with a Baroque-style onion dome with an iron double cross.
