The inscription on it warned during the blockade: "Citizens! During shelling, this side of the street is the most dangerous!"

The city was not only bombed from the air. The enemy was so close that you could see the dome of St. Isaac's Cathedral through binoculars. Artillery batteries shelled Leningrad every day. Shells exploded in the streets. So inscriptions appeared on houses warning residents that it was most dangerous to be on this side of the street during shelling.

It is quite possible that this discreet inscription saved someone's life. By the way, there are only 4 such signs left in the city - on the walls of house №14 on Nevsky Prospect, house №. 61 on Lesnoy Prospect, house № 7 on the 22nd line of Vasilievsky Island and house №. 6, building 2 on Kalinina Street. During the siege, Leningrad was shelled from the south, so the north-eastern and northern sides of many streets were especially dangerous.
