The panorama of Cathedral Square includes the five-domed Assumption Cathedral (the original building of which was built in 1382 in memory of the victories of Russian soldiers on the Vozha River), a 40-meter hipped bell tower erected in 1692, and the five-domed winter Tikhvin Church adjoining it.
The brick two-story building, built in 1865, is the former parish cathedral school, where school No. 3 now operates. Between the school and the bell tower on May 23, 2007, during the celebration of the All-Russian Days of Slavic Literature and Culture in Kolomna, a monument to the holy Equal-to-the-Apostles brothers Cyril and Methodius, created by the Honored Artist of the Russian Federation Alexander Rozhnikov, was opened.
