Muzeum Górnośląski Park Etnograficzny
Large skansen or open-air museum, with old farm buildings, dwellings and so on collected from around the region. Not much visible Nov-April as buildings are shuttered up against the winter. Its centrepiece was intended to be the 16th century church of Syrynia, but somehow that landed up in Katowice, and it's too frail to move again. Guided tour is available, but the accuracy of the guide's explanation is questionable at best.
A large theatre.
Kościół Marcina Lutra
The Protestant church was built from the 1890s in neo-Gothic style. The exterior is fairly plain but it's ornate within.
Muzeum Hutnictwa w Chorzowie
Large modern museum exhibiting the local steelmaking industry.
Large stadium, rebuilt 2009-17 to have a capacity of 54,378. It formerly hosted the national soccer team; it no longer has a resident team but stages athletics events and rock concerts.
Small museum in city centre.
