Since the early 1980s, thanks to the collaboration of actors and directors such as Roberto Milani, Nico Fazzini, and Fabio Bonso, it has hosted theater workshops, diction and mime courses, mask-making, and theatrical machinery construction that led to the staging of plays such as Lysistrata by Aristophanes and The Threepenny Opera by Bertolt Brecht. It has hosted the Documentation Center of Music and has been the home of the choir La Gerla, the choir Euterpe, and a theater company.
The park of Villa Simion extends over about six thousand square meters on the south side of the Library. There are over two hundred plants, both native and non-native.
In addition to small mammals like hedgehogs and shrews, the presence of the great spotted woodpecker has been noted for several years. Sightings of jays and common squirrels (red squirrel) are not rare.
The park is equipped with benches, a gazebo, and it is illuminated along the entire path that runs through it.
The exhibition space in the Oratory of Villa Simion has been hosting exhibitions organized by the Culture department and the Library of Spinea for several years, mainly dedicated to local associations and artists.
The Villa and the adjacent Oratory were acquired by the Municipality in 1967.
