Nearby to Saint Nikolas Church there is a Church and Monastery of Saint Onuphrius (Monastyr Svyatogo Onuiriya) dates back to hoary antiquity. Saint Onurfy Church began late in the 13th century as a wooden church that existed at the time of Prince Lev Daniilovich. In the mid-15th century it was supplemented by a monastery of Orthodox monks. Following a fire the church was rebuilt in 1518 by the Voivode (military leader) of Kiev, Prince Constantine Ostrozhsky. Numerous changes in the 17th and 18th centuries have contributed to Saint onuphrius (sometimes refferd as Saint Onurfy) Church present appearance. One can still see the remains of the defense walls that engirdled the monastery in the mid-16th century. The exterior of this church and to a certain extent even its constructional lay-out have been greatly altered. Thus today we can see only the general tendency of Saint Onurfys’ original structure and a few of the remaining details. It was built according to the cruciform plan typical of Ukrainian architecture; the narthexes are topped by two cupolas. The side naves, the apses and the belfry were built in the 17th century, the Trinity Chapel (Chasovnya Svyatoi Troitsy) – in 1701. The simple forms of ancient Russian architecture devoid of all exuberance are harmonically blended with the Italian Renaissance style and decoration in the portal and the adjoining sides, the pilasters and windows with arches made of stones from the Castle walls. Great value are the 17th and 18th century paintings: the Apostles over the Holy Door and the iconostasis of the Trinity Chapel.
