Unless the weather is just too good to miss, head back to Piazza del Duomo for the three-in-one Museale di SantaMaria della Scala, which is, even at a jog, a two hour indoor commitment.
Continue towards Campo di SantaMaria del Giglio, an area just west of the Piazza San Marco, where Woody Allen stalked Julia Roberts in the light-hearted comedy Everyone Says I Love You, then turn north to the theatre Teatro La Fenice and the nearby Ponte Maria Callas bridge, dedicated to American-born Greek opera singer Maria Callas who debuted at the theatre in 1947.
