Estádio Alfredo Jaconi

Estádio Alfredo Jaconi opened on 23 March 1975, timed to the centenary of Italian immigration into Rio Grande do Sul, on the same plot Juventude had bought back in 1919 for its original ground, the Quinta dos Pinheiros. The name it carries now dates from 1954, given two years after Alfredo Jaconi — player, coach and club president through the 1930s and 40s — died; the 1975 rebuild kept his name on the new structure.

Capacity at opening was 30,519. What the ground holds today is a smaller, more complicated number: current certification allows around 18,000, well short of the 25,000 the club had planned for when it modernised the site in 2021 for the return to Série A, because the number of emergency exits does not clear the requirement. That renovation replaced the pitch, rebuilt the dressing rooms, added a doping-control room, fitted tip-up seating and switched the floodlights to LED.

The record crowd stands at 27,740, for the Série A quarter-final against Grêmio on 27 November 2002, which Juventude lost 0–1 — the closest thing the ground has to an official high-water mark, since an older, larger figure quoted for a 1994 Série B semi-final against Americano-RJ was never confirmed.

The pitch is natural grass, and the stadium belongs outright to Esporte Clube Juventude, which has played there without interruption since 1975.
