If you're in Pisa on the 24th/25th of March then you can see in Pisa's second (or first, if you're a patriotic local) New Year.
The tradition dates back to the glory days of Pisa as a mighty maritime republic and, in an Indiana Jones moment, the new year is said to begin when a sunbeam breaks through a specially placed window in the cathedral, lighting up a precisely positioned marble egg.
Cue lots of kissing, medieval costumes, marching, flag throwing and carousing. The main venue is clearly the cathedral, framed as it is by the Leaning Tower and the splendid baptistry in the 'Field Of Miracles'.
The tower, alongside the cathedral, finally free of all scaffolding and gleamingly white as of early 2011, may be ascended and you can book at the official site or use the second site below if you'd like to book for a date further in the future than allowed on the official site.
