The first building on Polish territories built with bricks (before only wooden or stone building were erected) around the year 1188. The church was erected for the Johnnites order, who were running a hospital for the poor people nearby. The entrance is free, but as well limited to moments before or after services. This is also the only place in the city, where holy masses for dead people take place.
Huge zoo for a casual stroll located in a forest, large variety of animals (including elephants, tigers, seals and bisons) on spacious enclosures. Long distances may be a bit boring or tough on children. Zoo became popular for its focus on animal welfare and protection. You can access it also with park train (see below). Avoid restaurants inside zoo though, they are quite bad.
A late-Romanesque church (with some Gothic features) in the middle of Środka Market Square, nowadays a side-church for the cathedral parish. It is hard to get inside, unless you come approx. a quarter before or after services.
