A popular meeting place.

A famous square, real Sofia center with a monument of writers father and son Slaveykov. It`s a biggest open-air book market in the Balkans.There are round benches and street musicians act very often.

Half tour, half experience. Walk around a house setup like an old communist flat from the 1980s. You're allowed to touch and play with just about anything. There's an audio guide in English, Spanish and Bulgarian.

An obelisk built by the Russians.
