PalaLido, indoor arena in Milan

PalaLido, also known as Allianz Cloud Arena, is an indoor arena in Milan with around 5,400 seats and a floor that can be adapted for different sports or events. The roof, made of steel and polycarbonate, curves over the building and gives it a rounded outline that stands out from the surrounding neighborhood.

Designed in 1956 by engineers Giovanni Manfredi and Gaetano Ciocca with architect Aldo Paladini, the reinforced-concrete arena opened on 25 October 1960 with fencing, boxing, tennis and cycling displays. Basketball debuted there on 8 December 1960 before over 5,000 spectators. A rebuild begun in 2011 stalled through several contractors; Allianz won the naming bid in 2018 and the arena reopened on 21 June 2019 during the Volleyball Nations League.

The arena's sponsored name, Allianz Cloud, was chosen in a February 2018 tender won by the insurer Allianz, which held the naming rights for five years. The building itself is still widely called PalaLido, from the surname of architect Aldo Paladini, who collaborated on the 1956 project with engineers Giovanni Manfredi and Gaetano Ciocca.

The arena sits in Milan close to several public transport stops and is easy to reach by metro or bus. It is worth arriving a little early, as the streets around it tend to fill up before events begin.

The 2001 Milan Indoor, the tournament's last edition, was the first ATP title of Roger Federer's career, won on this arena's floor. The venue also hosted the 24th Italian Women's Volleyball Super Cup on 16 November 2019, and from 2019 to 2022 the Next Generation ATP Finals.
