Located in the northern part of the country, high above sea level, Ulan Bator is the coldest capital city in the world. The cultural and business center of Mongolia, and a hub connecting the Trans-Siberian Railway with the Chinese rail system, Ulan Bator has become a thriving urban center in one of the most remote locations in the world. Visit the Tibetan-style Gandan Monastery, one of the few buildings in Ulan Bator to predate WWII and one of the few monasteries to survive the Soviet purge.
