If soccer is the top Italian sport, it might be argued that Juventus is the top Italian team. So there's no better place to see them than at their home stadium in Turin.
Juventus Stadium was opened in 2011, built on the site of Juventus' former stadium, and can hold 41,000 people for a soccer game. It was built to high environmental standards, including producing its own electricity through solar panels and rainwater collection and reuse.
Even if you can't see a soccer game while you're in Turin, you can visit the team's museum at the stadium, known as the J-Museum, which opened in 2012. You can also take a guided tour of the stadium, which are conducted daily. You can pay extra to have your tour led by a “Juventus Legend,” too.
The museum at Juventus Stadium is open Wednesday through Monday from 10:30 a.m. to 7 p.m. in summer. Tickets for just the museum are €12 for adults (combined tickets with a stadium tour are €18, and a “Legends Tour” is €99). Tours run Monday and Wednesday through Friday at 11 a.m., 12:30, 2:45, 4:20 and 5 p.m. On holidays and weekends, tours start more frequently throughout the day. Shuttle bus 9 will take you directly to the stadium from Porta Nuova or Porta Susa train stations on matchdays.
