In the eastern frontage of the Rynek, adjacent to the Grodzka Street, which cuts across the eastern frontage, there are two very interesting tenement houses. Around the second-floor windows of the houses stone decorations have been preserved; they used to be part of the parapets, which topped the houses when they were lower, one-storey houses. The one on the right, called The St. Kazimierz Tenement House is additionally decorated with a sculpture featuring St. Kazimierz. This is how the owner of the house, Zamość alderman, Kazimierz Lubecki, honoured his patron saint over 300 years ago.
