Mikołów is one of the few cities in Upper Silesia which has the Old Town with a market square and streets branching off from it. The center of the town was completely renewed in 2002, including the reconstruction and modernization of the market square itself. There is a beautiful fountain in the center of the market square, its shape reflects this part of the town. Granite slabs on its south side correspond to the outline of the previous town hall. The spot where the oldest well in town used to be was marked out in a similar way.
The square is surrounded by tenements dating back to 18th and 19th centuries, with many still having the original architectural elements. The present town hall is housed in a building which is a part of the square’s western frontage and dates back to 1872.
There is a beautiful Art Nouveau tenement dating back to the beginning of the twentieth century opposite the town hall (Rynek 4). Its facade is decorated with bright low reliefs in window frames contrasting with yellow and orange bricks, as well as a half-timbered wall. The building is topped with a turret and a spire. Beautiful buildings can also be found at Jan Paweł II Street which leads away from the market square, tenement at no. 10 deserves particular attention. Its rich facade is decorated with mascarons and brilliant plant motifs.
