Zagreb Cathedral was first built in the 11th century in 1093. But this original building was destroyed during the Tartar and Mongolian invasions in 1242. The current neo-Gothic building dates back to 1880 when the cathedral was rebuilt after being severely damaged by a violent earthquake.
Religious heritage in Croatia's capital city dates back to its founding when the town of Gradec merged with the neighbouring canonical settlement of Kaptol which was the seat of the regional diocese. Since then, the city remained an important place for philosophy and theology. Furthermore, its location as an important city under the multicultural Austro-Hungarian empire and the multi-religious Yugoslavia gave it quite a variety of religious heritage sites that can be enjoyed today.
St. Mark's Church, whose current building dates from the 14th century, is one of the oldest buildings in the city of Zagreb. The church is classified as a cultural property of the Republic of Croatia.
The Church of St. Mary dates from the 14th century. In 1740, some baroque altars were added to the building. The church owes its current state to the renovation that took place after the earthquake in 1880.
The Church of St Catherine of Alexandria is the most famous Baroque church in Croatia. It was built between 1620 and 1632 on the site of a small 14th-century Dominican church. In the 17th century, the Jesuits, to whom the previous church had been given, completely rebuilt it. In addition to the church, they built a monastery (where the Dvori gallery Klovićevi is located today). After the abolition of the Jesuits in 1773, the St Catherine church was ceded to the parish of Saint-Marc in 1783 and became a university church in 1874.
The Cathedral Church of the Transfiguration in Zagreb is the cathedral of the Serbian Orthodox Church. The building was built in 1866 on the site of an old Catholic church, St. Margaret's, mentioned since 1334 and sold to the Orthodox in 1794.
This mosque was completed in 1987 in the Trstik housing complex in order to accommodate the large amount of Muslims living there. The mosque is built in order to follow modern construction trends of the time rather than following traditional Arabesque architecture. The building contains a 51m high minaret, a religious school, a library, and other features.
