Only in 1867, do we witness the first important change of ownership: by virtue of the so-called Siccardi Law, the Abbey becomes the property of the Municipality of La Morra.
Renato Ratti rents the Abbey in 1965. At the onset, the spaces are destined to the production of Barolo, but then, in 1971 the rooms host the exhibitions of the Renato Ratti Museum of Barolo and Alba wines.
