The Gallizia mill is one of the old mills built by the monks that lived and worked here. Nowadays, the house (the mill) hosts the Paper Museum and Museum for Print. Basels Paper used to be famous, and many medieval scholars let their books print here.
In the museum, you can watch how to make paper (and do some yourself). It is very much worth a visit. In the surrounding area, you can find many old and well-restored and renovated buildings. It is a nice place for a walk.
