The Georgi Dimitrov mausoleum in Sofia, the capital of Bulgaria, was built in 1949 to contain the embalmed body of the country's first communist leader.

After the fall of the USSR, some members of the government started thinking the monument was an embarrassing nod to Bulgaria's totalitarian past, and in 1999, they decided to blow it up. But though the mausoleum had been built in only 6 days, it took four attempts to destroy it.
