Św. Jana (St. John's) Street is one of the oldest in Katowice. Its buildings are mostly well-preserved eclectic townhouses from the turn of the 19th and 20th centuries. It owes its name to the figure of a saint visible near the intersection with Staromiejska Street, placed here in 1816 (the current sculpture is a replica of it). In the 1960s, the AMFORA drugstore opened its doors on the ground floor of the corner tenement house. At the time, it was one of the best-stocked stores of its kind, successfully competing with nearby department stores like Zenit, PDT, and Skarbek. The Amfora drugstore operated almost until the end of the 20th century. Currently, there are completely different commercial premises in this location. However, it's pleasing that several new, successful neon advertisements have been created in the area recently.
