The Georgi Dimitrov Mausoleum () was a ceremonial tomb on Prince Alexander of Battenberg Square in Sofia, Bulgaria. It was built in 1949 to house the embalmed body of Georgi Dimitrov, the first leader of Communist Bulgaria. After his death in 1950, the second communist leader of Bulgaria, Vasil Kolarov, was buried in the second niche of the east wall of the mausoleum. In 1999, following a heated public debate, it was destroyed by Ivan Kostov's UDF government. Construction The white marble mausoleum was built in 1949 to contain the embalmed body of the first leader of Communist Bulgaria, Georgi Dimitrov (1882–1949); construction beginning immediately after the news of Dimitrov's death. It was completed in just six days, the time it took Dimitrov's body to be returned to Sofia from the USSR. Dimitrov's body remained in the mausoleum until August 1990, when Dimitrov's remains were cremated and the ashes buried in Central Sofia Cemetery. Attempt to blow up the mausoleum In 1956, 14 anti-communists prepared a bombing of the mausoleum during a May Day demonstration. Clock bombs would have exploded after the leadership of the Bulgarian Communist Party and the country came on the podium. The act, which was planned by Stoyan Zarev, was intended to draw the attention of the world media to Bulgaria. In addition to the Mausoleum, Zarev also planned to blow up five important ministries. The group encountered difficulties in implementing the plan and was greatly delayed, until they were uncovered and arrested by the KDS in February 1960. Maintenance and activities The mausoleum was an object of police protection of paramount importance. The mausoleum was the center of state ceremonies in the People's Republic of Bulgaria, a place where foreign delegations lay wreaths when visiting the country and the state leadership from its rostrum receives the demonstrations and parades on the official holidays. The Bulgarian Land Force's National Guards Unit formerly performed public duties at the now destroyed mausoleum, in a ritual similar to today's changing of the guard at the Presidency. The guards at the mausoleum were part of Post №1, which was mounted on Sundays, Wednesdays, and on solemn occasions. Soldiers were selected from the Bulgarian People's Army as well as the Internal Troops of the Ministry of Interior. There were no cartridges in the rifles while on duty, as police were always on duty in the area. In 1974–1975 a major reconstruction
