Starting September through December, Italy's major state museums will be open (free admission) from 7 PM-11 PM. The main reason is to promote the arts to underprivileged Italian citizens, but this is also a great opportunity to visit some of Italy's legendary art and archeological sites and museums without having to pay the steep fees in cities such as Rome, Naples, Milan, and Florence. Although it would have been nice if the Veneto extended the program to other sites outside of Venice in places such as Padova (the Scrovegni Chapel), Vicenza (the Teatro Olimpico or the Rotonda), or maybe even Petrarch's house in Arqua Petrarca, I am looking forward to visiting the Gallerie dell'Accademia or Ca d'Oro at night, hoping to experience something as fantastic as Florence's Palazzo Vecchio at night.
Participating sites in Venice include:
Galleria "Giorgio Franchetti" alla Ca' d'Oro, Cannaregio, 3932 - Venezia (VE)
Gallerie dell'Accademia, Dorsoduro Campo della Carità, 1050/a - Venezia (VE)
Museo Archeologico di Venezia, Piazza San Marco, 52 - Venezia (VE)
Museo d'Arte Orientale, Santa Croce, 2076 – Venezia (VE)
