A memorial plaque dedicated to the Holy Martyr Nicholas, Bishop of Sestroretsk, was unveiled on July 9 on the facade of the church of the Tikhvin Icon of the Mother of God of Sestroretsk.
Rector Archimandrite Gabriel (Konevichenko) recalled that shortly after the return of the Tikhvin Icon of the Mother of God in 2004, a temple was built in honor of the icon on the Forecourt of Sestroretsk, and a year later, on July 9, the first patronal feast was held there.
