(Photo of work Italian Scenery by George L. Brown from 1846 in the Smithsonian American Art Museum collection and the photo in the public domain because the work is more than 100 years old)
You can read my English translation of excerpts from the announcement of this event.
I read an article about the upcoming Giornate FAI di Primavera, the annual event put onby the FAI ( Fondo Ambiente Italiano ) organization opening up places to discover all throughout Italy. If you are in Italy this weekend, you are in luck!! It sounds like there will plenty of interesting places to visit for free.
Ci sentiamo presto, Lina
