Padova is a city and comune in Veneto, northern Italy. Padova stands on the Bacchiglione River, 40 kilometres (25 miles) west of Venice and 29 km (18 miles) southeast of Vicenza. The Brenta River, which once ran through the city, still touches the northern districts. To the city's south west lies the Euganaean Hills, praised by Lucan and Martial, Petrarch, Ugo Foscolo, and Shelley. Padova appears twice in the UNESCO World Heritage List : for its Botanical Garden, the most ancient of the world, and the 14th-century Frescoes, situated in different buildings of the city centre. An example is the Scrovegni Chapel painted by Giotto at the beginning of 1300. The city is picturesque, with a dense network of arcaded streets opening into large communal piazze, and many bridges crossing the various branches of the Bacchiglione, which once surrounded the ancient walls like a moat.
