Located in a vast alluvial plain, four meters above sea level, a few kilometers from the Tyrrhenian coast, Pisa (approx. 92000 inhabitants) extends along the two side of the Arno. One of the major cultural centers of Italy, Pisa contains a rich artistic patrimony, with medieval re-elaborations of Islamic, Lombard and local influences. Capital of the Tuscan province and headquarters of the episcopality, the city today is a prestigious university and research center, with an economy primarily focused on the tertiary sector (computers, tourism, and services), alongside the textile, glass, chemical, pharmaceutical and mechanical industries.
