The house got its name from a Baroque bas-relief located in the niche of the 1st floor façade. It was built in the 17th century and was owned alternately by Polish chemists and Armenian merchants. There is a figure of St. Casimir, the saint patron of the new owner – Kazimierz Lubecki, on the façade of the house. The original layout of the rooms with a hallway in the middle has been well-preserved.
