The Joan Oller printing house is one of the 8 museum spaces of the project of the old shops of Calaf. This place is a faithful recreation of the printing press that worked in the same place from 1939 to 1977. The printing machine (Minerva) from the beginning of the century, like the guillotine, works perfectly with all its original components. All the necessary elements for the elaboration of texts are conserved. A whole series of essential elements for a 20th century printing press complete this fantastic space.
