This is an abandoned escalator building in Vorobievy Gory (Sparrow Hills). What you see here are the remains of the three former escalators. The building was opened in 1959 as a quick way for people to reach the top of the hill. It was closed in 1983, due to structural defects, and was never re-opened, as you can see! Now it sits graffiti covered (and currently ice filled!) as a reminder of the past.
