Cathedral of Three Saints is just one of the landmarks located 0.8 mi (1.3 km) from central Mahilyow, so you might want to stop by for a few pics during your trip.
If museums are on your list of things to see in Mahilyow, then you might want to head to Mogilev Museum of Art. If you want to experience more of the culture Mahilyow has to offer, head to Cathedral of Three Saints and Pechersk Lake Park.
