Kremlin Wall

Tourists at the wall.  There are a 108 men and 7 women interred in the wall itself (including the first man in space, Yury Gagarin).  There are also 12 individual tombs.  And heaps more people buried in mass graves in front of the wall.  There's a complex history to it.  The last interment at Red Square took place in 1985.  Only two of the Soviet leaders are not buried at Red Square: Khrushchev, because he was out of favour when he died and is buried elsewhere in Moscow, and Gorbachev - because he is still alive.

PS:  Another glimpse of the wall - which gives an idea of the height - in this blip on 3 August 2016.
