Villa Borghese, in the heart of Rome, is 5.5km (3 1/2 miles) in circumference. One of Europe's most elegant parks, it was created by Cardinal Scipione Borghese in the 1600s. Umberto I, king of Italy, acquired it in 1902 and presented it to the city of Rome. With lovely landscaped vistas, the greenbelt is crisscrossed by roads, but you can escape from the traffic and seek a shaded area under a pine or oak tree to enjoy a picnic or simply relax. On a sunny weekend afternoon, it's a pleasure to stroll here and see Romans at play, relaxing or in-line skating. There are a few casual cafes and some food vendors throughout; you can also rent bikes here. In the northeast of the park is a small zoo; the park is also home to a few outstanding museums.
