Yup.....it started last month and runs through December. I found this info on www.firenze.net but I need to give an avviso: the web site says it's for "fiorentini." And let's be honest, that's easy to verify. Just listen for the 'c' that never arrives. And it appears to refer to two specific areas of the museum, not the whole place.
But for all of you foreigners in Italy who have put off a visit to the Uffizi because of the sheer magnitude of such an undertaking or because of the line, it's worth a try to see if the free admission extends to everyone.
According to Firenze.net, i fiorentini "potranno visitare con la guida di esperti due parti assai significative degli Uffizi. Si tratta della ex chiesa di San Pier Scheraggio e della Collezione Contini Bonacossi." Wow that's pretty cool!
