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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
