The biggest congress center in the Balkans (a massive monolithic communist-style building). If asking for directions, ask for NDK (en-de-ka), as most Bulgarians refer to it by this acronym.

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.
