First mentioned in documents in the year 862 as an already important settlement, by the 10th century Rostov became the capital city of Vladimir-Suzdal, one of the most prominent principalities in Rus'.[16] An area situated between the cathedral square and the lake was chosen by Iona Sysoevich as a place for his fairy-tale residence.The residence, often erroneously called kremlin, also includes eleven ornate tower bells, numerous palaces, several small belfries, and the diminutive baroque Church of Our Lady of Smolensk (1693).Its cathedral, commissioned by Ivan the Terrible in 1553 to commemorate the conquest of Kazan, inspired numerous churches in the region, particularly in Yaroslavl.Spaso-Yakovlevsky Monastery, situated to the left from the Kremlin on the town's outskirts, has been venerated as the shrine of St. Dmitry of Rostov.One of the best preserved monasteries in Russia, named after the saints Boris and Gleb, is situated in Borisoglebsky, about 20 kilometers (12 mi) west of the town.The monastery was favored by Ivan the Terrible, who personally supervised the construction of towered walls and bell-tower around an even more ancient cathedral.The only addition made to the monastery after Ivan's death is a barbican church, commissioned by the metropolitan Iona Sysoyevich.
