Parco Centrale del Lago, Urban park and artificial lake in EUR district, Rome, Italy.

Parco Centrale del Lago is a park in Rome's EUR district, split roughly equally between green space and an artificial lake of about 80,000 m². The basin runs perpendicular to via Cristoforo Colombo, is 60 to 130 m wide and 2 to 4 m deep, and is closed at its short ends by the UniCredit bank building and the ENI tower. A hill with the Palazzo dello Sport rises above the lake, with waterfalls at its base.

The park was planned from 1937 as part of the EUR 42 universal exhibition project, with Raffaele De Vico and Marcello Piacentini involved and an artificial basin already foreseen. The executive group formed in 1939, but Italy's entry into war and the fall of fascism in 1943 halted work. De Vico resumed after the war with engineer Giorgio Biuso, and the lake was built as a basin about one kilometre long, 60 to 130 metres wide and two to four metres deep.

The pedestrian and cycle path through the park is named Passeggiata del Giappone after Japan's prime minister Nobusuke Kishi, who in July 1959 donated 2,500 flowering cherry trees to Rome; many were planted here. Romans now hold hanami picnics under the blossoms from mid-March to early April, some wearing kimono.

The park is easy to reach on foot and has several entrances spread around the lake. Visitors can walk the perimeter or spend time at quiet spots without needing advance reservations.

The lake is continuously aerated through a system of water features that keep it moving and healthy. This practical engineering solution is often overlooked by visitors who focus only on the garden's appearance.
