The Molí d'en Rata Heritage Interpretation Centre (), in Ripollet (Vallès Occidental), is a municipal facility dedicated to research into and the conservation, management and diffusion of the heritage of Ripollet. It encompasses two areas: the Molí d'en Rata (En Rata mill), one of El Vallès Occidental’s last operational flour mills, and the Heritage Interpretation Centre, a newly constructed building with two exhibition rooms: one for the permanent exhibition and the other for temporary exhibitions. It is part of the Barcelona Provincial Council Local Museum Network.

Permanent exhibition
The interpretation centre's permanent exhibition includes three areas:
