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 Church of St Eustace was built between 1532-1632. St Eustace"s is considered a masterpiece of late Gothic architecture. The church’s reputation was strong enough of the time for it to be chosen as the location for a young Louis XIV to receive communion. Mozart also chose the sanctuary as the location for his mother’s funeral. Among those baptised here as children were Richelieu, Jeanne-Antoinette Poisson, future Madame de Pompadour and Molière, who was also married here in the 17th century. The last rites for Anne of Austria, Turenne and Mirabeau were pronounced within its walls. Marie de Gournay is buried there.
The origins of Saint Eustache date back to 13th century. The church became a parish church in 1223, thanks to a man named Jean Alais who achieved this by taxing the baskets of fish sold nearby, as granted by King Philip Augustus. To thank such divine generosity, Alais constructed a chapel dedicated to Sainte-Agnès, a Roman martyr.
