It is considered the tallest structure in Croatia. Originally a medieval cathedral got its neo-Gothic look after the earthquake, the large reconstruction (1880th to 1902nd) under the guidance of architect Hermann Bollé and Friedrich von Schmidt. The chapel of St. Stephen (now the Bishop's Palace) has been preserved from medieval times with its Gothic frescoes. In the sacristy of the cathedral is the Calvary altarpiece, the work of the famous painter Albrecht Dürer. Zagreb Cathedral is proud of its rich treasury which holds the mantle of King Ladislas from the 11th century. Around the cathedral are the Renaissance walls with circular towers, where the Bishop's Palace was built during the baroque era, the time of Bishop George Branjug.
