Ulaanbaatar is the capital city of Mongolia, located in the North-central area of the country, and is surrounded by the province of Töv.
While there is evidence that the region around Ulaanbaatar was inhabited up to 300,000 years ago, the first settlement was established in 1639, and was known as Örgöö. Örgöö, meaning "palace-yurt", was a mobile town and monastery that change locations every few years, between 25 and 28 times, until it permanently settled in the current location of Ulaanbaatar in 1778.
No fossils are yet known from the city of Ulaanbaatar, but it is home to the Central Museum of Mongolian Dinosaurs, which showcases numerous dinosaurs discovered in Mongolia.
Ulaanbaatar, derived from the classic Mongolian "Ulaganbagatur" which translates to "Red Hero", was named to honour Damdin Sükhbaatar in 1924. Damdin played an important part in the liberation of Khüree (now Ulaanbaatar) from China during the Outer Mongolian Revolution of 1921 with the help of the USSR. Because of this, he was named the "Father of Mongolia's Revolution", or the "Red Hero".
