12 Krakowska Street in Tarnowskie Góry, Historical house at Krakowska Street, Tarnowskie Góry, Poland

The building at Krakowska Street is a three-story structure with decorative window sills, characteristic corner tower elements, and a mansard roof covered with ceramic tiles. The corner section connects the side facades through a tower-like element topped with a low ceramic-tiled crown.

The corner building existed by the 18th century; in 1765 it was valued at 313 thalers. In 1865 the merchant Adolf Schlesinger had farm buildings erected on Tylna Street. From 1908 the master baker Heinrich Siedner owned it, and in 1911 the mason Walter Wichura rebuilt it, retaining parts of the old walls and cellars. It was listed as a monument on 29 August 1994.

The portal above the entrance carries a relief of a ship, a reference to the medieval Hanseatic League. The corner holds a four-storey hexagonal pseudo-turret under a six-sided roof, and the facade's outer axes end in cartouches with coats of arms. The building was listed as a monument on 29 August 1994.

The building stands at the corner of Krakowska and Tylna streets in the city centre, with its main entrance on the nine-axis Krakowska facade. The rear wing faces Tylna Street, whose mouth was widened when the eastern part was demolished in 1911. The interior staircase is original, with a steel structure, wooden treads and a metal balustrade.

The corner tower element is often overlooked but represents a rare architectural detail from that era in the region. This type of corner treatment was uncommon and shows the craftsmanship applied to the building.
