Zagreb Cathedral, also known as the Cathedral of the Assumption of the Blessed Virgin Mary, is a Catholic cathedral located in Zagreb, the capital city of Croatia. The cathedral is situated in the city's Kaptol neighborhood, which is known for its medieval architecture and religious landmarks.

The cathedral was first built in the 11th century but has undergone many renovations and restorations over the centuries, most recently in the late 19th century. The current neo-Gothic structure was completed in 1906 and features two tall spires that rise 105 meters (344 feet) above the city skyline.

Inside, the cathedral is adorned with beautiful stained glass windows, intricate carvings, and several altars. The most notable feature of the interior is the altar of the Blessed Alojzije Stepinac, a Croatian cardinal who was beatified by the Catholic Church in 1998.

Zagreb Cathedral is a popular attraction for tourists and locals alike, not only for its religious significance but also for its architectural and historical importance. It is the tallest building in Croatia and one of the most recognizable landmarks in Zagreb. It is also a popular venue for classical music concerts and other cultural events.
