16 Market Square in Tarnowskie Góry, Historic townhouse on the Market Square in Tarnowskie Góry, Poland

The house at number 16 is a classical residential building on the Market Square of Tarnowskie Góry with a traditional facade and symmetrical windows. The structure shows typical features of residential architecture from several centuries, with solid walls and well-maintained details.

The house was built in the 16th century, but neither its founder, architect, nor exact construction date is known. In 1673–1676 it belonged to Marcin Niwko, and it burned in the town fire of 1746, when it was valued at 570 thalers and owned by Dr. Jacob Karol Psczenski. From 1791 it belonged to merchant Johann Sedlaczek, founder of a winery, and in July 1804 it hosted Józef Wybicki, author of the Polish national anthem. It was listed as a monument on 27 April 1966.

The narrow lane separating numbers 16 and 17 was officially named Böhmgasse in the second half of the 19th century after the Böhm family, who owned this house from about 1864; it is now Przesmyk Street. On the ground floor a fish shop traded for several decades until 2013, and today the building houses a jeweller, an ice-cream parlour, a law office and a variety shop.

The house stands on the western side of the Market Square, at the corner with Przesmyk Street, next to number 17. The ground floor now holds a jeweller, an ice-cream parlour, a law office and a variety shop, so the front is best seen from the square. Traces of the former arcades survive inside the ground-floor rooms.

The arcades that once fronted the house are gone from later maps and photographs, but their traces survive inside the ground-floor rooms. The narrow lane separating numbers 16 and 17 was officially named Böhmgasse after the Böhm family; it is today's Przesmyk Street.
