Sofia is one the most intersting eastern European capitals. The area had human population sinc the year 7000 BC, so it means a lot of different cultures and religions passed through this land.
St. Alexander Nevsky Cathedral, is one the most remarkable ones. This Orthodox church cathedral built in a Neo-Byzantine style, is one of the largest ones of its kind in eastern Europe.
I had the opportunity to visit sofia in the Autumn of 2016 and I really like this city that I would love to visit again.
