The most impressive square in Livorno is actually a sort of bridge over the main canal. It seems far too large for a place like Livorno, far too grand...and very empty. Two larger than life statues face off each other across the length of this huge piazza, but I forget who they are...
One one side, a busy road separates the piazza from the canal facing the Fortezza Nuova. The canal branches off and travels under the piazza, emerging on the other side to form a sort of moat around the centro storico. Just next door to Piazza della Repubblica is Piazza Garibaldi, a smaller version with a statue of Garibaldi.
If this piazza was in any other Tuscan city, there would be overpriced outdoor cafes and portrait artists and mime artists and buskers. But Livorno has none of this. In fact, we couldn't find a single cafe around the square...and by that time, I needed a shot of coffee!
The best views are to be had from inside the Fortezza Nuova...tramp through the undergrowth and scramble up the wall behind the playground, and Piazza della repubblica spreads out before you.
