Known as Padova in Italian, Padua may be the oldest city in northern Italy, if you believe the claims of its 12th-century BC founding by Trojans. It certainly has history, including its famous university (one of Europe’s oldest, from 1222), the 13th-century Basilica di Sant'Antonio (resting place of St. Anthony), and Scrovegni Chapel, with Giotto’s famed 14th century frescos. The magnificent Prato della Valle, a 950,000-square-foot elliptical square, is thought to be Europe’s second-biggest.
