The Dormition Cathedral in Vladimir was a mother church of Medieval Russia in the 13th and 14th centuries. It is part of a World Heritage Site, the White Monuments of Vladimir and Suzdal.
The cathedral was commissioned by Andrew the Pious in his capital, Vladimir, and dedicated to the Dormition of the Theotokos, whom he promoted as the patron saint of his lands. Originally erected in 1158 to 1160, the cathedral, with six pillars and five domes, was expanded in 1185 to 1189 to reflect the augmented prestige of Vladimir. At 1178 m², it remained the largest Russian church for several hundred years.
Andrew the Pious, Vsevolod the Big Nest and other rulers of Vladimir-Suzdal were interred in the crypt of this church.
