With the financial mess Siena is in right now, you'd think free cultural events are a thing of the past. But quite to the contrary, they keep popping up all over the town. SATURDAY, 18th of May starts off with another appointment of RSVP, an initiative that brings contemporary art to the medieval heart of the city and some of its most beautiful privately owned buildings. From 4.30 pm to 8 pm you can explore a Siena most of us have never seen. Three generous and art loving house owners open the doors of their homes for the artworks of Vedovamazzei, Ettore Favini and Emanuele Becheri - and for you and me.
