Karlín is a Prague's district at the foot of the Vítkov hill. Notice also the gray building above the Karlín Studios on top of the hill...
It is National Monument at Vítkov Hill...

It was built in-between WW1 and WW2 (to commemorated the Hussite battle which took place on the spot in the Middle Ages and also the horrors of WW1), but after commie-take-over in 1948, the idea was to turn it into a mausoleum of the local leading Stalinist figure who died in 1953 (after coming back from Stalin's funeral).
The examples came from Lenin's Mausoleum in Moscow and the Georgi Dimitrov Mausoleum in Sofia.
However, Bohemians are not as good in mummification as Soviets (not to speak of Egyptians) and thus the unholy commie body began to rot and had to be cremated in 1962.Klement Gottwald's body was exhibited in the center of the Mausoleum in a glazed sarcophagus. The embalmed body was dressed in the blue general's uniform of the Head Commander of Czechoslovak armies. In 1958 it was changed to civilian attire.
In 2011, i saw in Karlín Studios exhibited f.e. this table...
and also this mural (made of staples)...
But again, it's all (table, staples, mummy) gone!
