Vladimir is a historic city in western Russia founded in 990 AD. It has a population of 340,000 and was formerly the capital of Rus in the 12th-14th centuries. Some of its most notable landmarks include the Golden Gate built in 1158-1164 as the main entrance to the city, and the Cathedral of the Assumption, a five-domed Orthodox church constructed in 1158-1160 that served as the main church of the region. Both landmarks are now part of the Vladimir and Suzdal museum and are UNESCO World Heritage sites.
