Greek Catholic Co-cathedral of Saints Cyril and Methodius is located in the Street of St. Cyril and Methodius on the Upper Town in Zagreb.
Greek Catholic church and seminary (built in 1681) existed on the Upper Town before the 17th century. This Church was intended for the Greek Catholic believers, mostly people from Žumberak Mountains, Uskoks and clerics that lived in and around Zagreb. It is not possible to determine when was this Church built because a fire that broke out in 1766 destroyed most of the Church's books that would give a precise date.
The current church dedicated to St. Cyril and Methodius was built in 1886 during the reign of Bishop Ilija Hranilović on the site of the former church of St. Basil. The parish uses the facilities of the Greek Catholic seminary that is connected to the Church which gives room that serves as a parish office, and, since 1932, a hall with sacristy.
Co-Cathedral was designed by Hermann Bollé. It is built in the neo-Byzantine style of historicism. Co-Cathedral owns a rich collection of paintings by Ivan Tišov, as well as icons by E.A. Bučevski and professor Nikola Mašić. There are three bells in the 50m high Co-Cathedral's belfry. Largest bell weights 782 kg and is dedicated to St. Cyril and Methodius, medium bell that weight 395 kg is dedicated to the Mother of God and small bell that weights 230 kg and is dedicated to Basil of Ostrog. Co-Cathedral owns a precious cross for tetrapod, reliquary, and two capes, as well as set of kit icon mounted on wood for the cross.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
