36 Hours in Sofia, Bulgaria - NYTimes.com - OMG, This is probably the best travel article on Sofia I've ever read. It even includes Hambara! A old barn/bar in the city center that is only lit by candles (could never exist in the western world due to fire codes). I really need to get back there soon.
The ancient Roman theatre of Philippopolis in the city center of Plovdiv (ancient Philippopolis), Bulgaria. According to a builders’ inscription, discovered on the frieze-architrave of the eastern proskenion, the construction of the theatre dates back to the time of Emperor Trajan (reigned 98–117 AD).
