On Saturday the 10th of December, many museums and cultural spaces will be opened in extraordinary mode from 8:00 pm to 2 am for free or at nominal cost of € 1.
Over all, the Capitoline Museums, the Macro and Macro Testaccio, the Museum of Rome in Trastevere, The House of Jazz, the Auditorium Parco della Musica, The Auditorium Santa Cecilia and the Academy of France Villa Medici.
A wonderful initiative promoted by the City of Rome: a unique opportunity to experience an amazing Saturday evening between music and art, surrounded by the artistic and cultural beauties of the city, to learn about new places or rediscover in robe night, to get involved with fascinating stories and see live art, to listen to great music and visit exhibits that maybe we could not see in ordinary time, or just to spend a Saturday evening unusual. All at the cost of 1 euro ticket or completely free admission, where expressly provided.
