The vicinity of Rostov is rich in old architecture. For example, an old wooden church (1687�1689) may be seen in the settlement of Ishnya. 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
