This square or maybe triangle is behind the cathedral. Each monk, who served in the cathedral, had his own house. Some of these monks were quite famous, like Stanislaw Staszic who was the co-author of the first Polish constitution it was in the year 1793 - Poland had the first written constitution in Europe.

A theory is that the square takes the name of Famous Ottoman emperor Suleyman the magnific which his name in turkish is Kanuni( the man of law)In 1533 Ottomans signs a treaty with Poland about the eternal peace and I think that Polish people give the name of Suleyman to this square.

The bell was brought to this place from the National Museum in 1972.
Originally casted in 1646 by Daniel Thiem, was intended for the temple in the town of Jaroslaw, but because of production fault it never rang as it was cracked in casting. Somebody left it at this spot a couple of hundred years ago…

In the corner you can see the narrowest house in Warsaw and Europe and one of the 10 narrowest in the world.
In the 17/18th centuries the tax from the house depended on how wide it was, so this was the reason they built rather high, but narrow buildings.
