The Tomb of Milan Rastislav Stefanik (Slovak: Mohyla Milana Rastislava Štefánika) is the Tomb of Slovak politician, diplomat, aviator and astronomer Milan Rastislav Štefánik. The mound is one of the most famous architectural works by Dušan Jurkovič. The mound is a 96 metres (315 ft) long and 70 metres (230 ft) wide structure. Its lower terrace, which has dimensions of 93 by 62 metres (305 ft × 203 ft) and two staircases, is terminated in the corners by fire chambers. On the upper terrace, which has dimensions of 45 by 32 metres (148 ft × 105 ft) and also two staircases, there are four 12.5 metres (41 ft) m high obelisks. The obelisks symbolize the four victims of the plane crash and at the same time the four countries in which Štefánik worked.
