A closer look
Built for the 1980 Moscow Olympics sailing events, this hulking concrete monstrosity in Estonia was originally named the V. I. Lenin Palace of Culture and Sports. Today, the brutalist amphitheater and ferry terminal is a graffiti-covered ruin slowly crumbling into the Baltic Sea. Urban explorers flock to climb its massive, stair-heavy exterior, essentially treating a colossal monument to Soviet megalomania as the world's bleakest jungle gym.
