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.
I have always wanted to visit Sofia and the opportunity came this year. I was visiting Vienna and decided at the last minute to spend a few days there. What an eye-opener it was! The city has much to offer. Lots of historical places to admire. Easy to travel around. The people are friendly. And, above all, quite reasonably cheap. The photo above is considered to be the biggest Orthodox Church in all of Bulgaria. It is called the Alexander Nevsky Cathedral.
