A sculpture commemorating the first Mongolian cosmonaut, Jügderdemidiin Gürragchaa, in Choir

Choir was a military base during the Soviet period. In 1989, the Soviet anti-aircraft missile units left Choir.[1] The longest runway in Mongolia, now abandoned, is located 25 km N from Choir, a relic of that period.[2] In 1992, the military cantonment passed into the jurisdiction of Govisümber Province, according to the 1992 constitution.[3] Near the railway station is a statue commemorating Mongolia's first cosmonaut, Jügderdemidiin Gürragchaa.
