This is the only Tuscan city in which the life of the river’s waters, now near the mouth, is really present. […]
Like all fluvial cities, Pisa is truly one with its surroundings, to which it seems linked by the subterranean life of the waters and the marine skies.
I think the most beautiful avenue in Italy is that of plane trees between Pisa and Bocca d’Arno along the river: on hot days the leaves seem to blow like animated genii, a breeze on who passes. At the mouth you can see the waters of two colors, bluer than those of the river, and those of the sea greener.
Behind the Apuan Alps rise up beyond the plain.
(Guido Piovene, excerpt from the book “Viaggio in Italia”, 1957)
