"The canonball at Stortorget"

In the corner house at Skomakargatan there is a memorial in the form of a cannonball that is visibly embedded in the facade and which gave that part of the Ceres quarter the name Huset Kulan. A folk tale tells that the bullet was fired there from Brunkeberg in connection with Gustav Vasa's siege of Stockholm in 1521 and was intended to kill Christian II as he sat in one of the house's windows, but missed its target. The ball was put up again when the house was rebuilt in 1795. The truth is, however, that Furniture Dealer Carl Adolph Grevesmühl had a Gustavian bourgeois house built in 1795 on the corner of Stortorget and Skomakargatan and it was he who then had the cannon ball bricked into the corner of his new house to symbolize Gustav The siege of Vasa which made Christian II surrender.
