The Zagreb Cathedral, or the Cathedral of the Assumption of the Blessed Virgin Mary, has a fascinating history, full of ups and downs. Back in 1093, when King Ladislaus I of Hungary decided to make Zagreb the bishop's seat, he chose the existing church to be the cathedral. Construction work began after he died and was finally completed in 1217, during the reign of King Andrew II of Hungary.

Throughout its history, the cathedral faced numerous challenges, including fires and attacks from enemies, which altered its construction. After the devastating Tatar invasion in 1242, the cathedral was reconstructed in the Romanesque-Gothic style. In the 15th century, protective fortification walls were erected, some of which still stand today. The cathedral also endured two destructive earthquakes in 1880 and 2020.

Following the first earthquake, the cathedral underwent a major transformation in the Neo-Gothic style from 1880 to 1906. This reconstruction gave the cathedral its current appearance with two elegant towers, a high roof, new pillars and altars in the sanctuary, replacing the 18th-century baroque ones. And twin 108 metres (354 ft) high spiers made the Cathedral the tallest building in Croatia.

Unfortunately, the recent earthquake in 2020 caused damage to both the exterior and interior of the cathedral, and repair is still underway.

The Zagreb Cathedral has a  marvellous concert organ renowned for its captivating romantic sound and is one of the world's top ten organs, recognised for its exceptional quality and excellence. Look out for an organ performance while you’re in Zagreb.
