Esztergom is a city in the north of Hungary, on the right bank of the Danube river, which forms the border with Slovakia, not very far from Budapest, and most accessible by city train. I went there after lunch, walk around the town, visited their cathedral and some other important sites, and then returned to Budapest for supper. Although the city seems to have been left behind, one can still appreciate the historicity of this place, which was once the capital of Hungary and the seat of the Primate of the Roman Catholic Church in the country.
Emperor Constantine built this ancient church. He loved Sofia so much, he wanted to make it the capital of the Byzantine Empire. The church is surrounded today by all these buildings because during the Communist era there was an attempt to hid religious sites from public view, so I am told.
This was once a thriving city. St. Paul wrote a letter to the Christian community. The 4th Gospel is believed to have been written here. It is one of the seven churches mentioned in the Book of Revelation. One of the great councils of the Church was held here.
Ephesus was once a great city. St. Paul wrote a letter to the Christians who live there. The Third Ecumenical Council was held there where the Church affirmed the Nicene Creed and declared Mary as Theotokos. Although the ancient city no longer exists, you can still admire its greatness as you walk through its ruins.
