The buildings on Number 18-20 were merged in the 17th century and subsequently named after Johan Eberhard Schantz, the secretary of Charles X Gustavus who also added the stepped gable and the grand portal on the left building.
The block on Number 14-16 is named after Æsculapius, the son of Apollo and the demigod of medicine, which reflects the presence of the "Raven Pharmacy" (Apoteket Korpen) at this address for more than 300 years.
