Even though it is the city's main cathedral, I am afraid it is a difficult building to like.
It is a late (completed in 1858) Neoclassical rendering of a Byzantine Greek-cross church. I think it looks a very austere structure on the outside.
Inside it is very different. It is all very Italian Baroque - except for its regular cross layout and the Iconostasis.
Obviously it suffered under the communists when it was turned into an Anti-religious Museum (!?!), being stripped of anything moveable or valuable.
The four main doors mimic Ghiberti's Baptistery doors in Florence.
The Great Dome - one of the highest of any church in Christendom - has a white dove sculpture in it.
