If you're a fan of live theater, make sure you go to a show at Centrale Alidos Theatre. Make a reservation to secure the best seats.
You'll have no end of sightseeing choices when visiting Quartu Sant'Elena. Centrale Alidos Theatre is a great place to start here, but there are many other interesting places to appreciate. Bastion of Saint Remy, National Archaeological Museum, and Roman Amphitheatre of Cagliari are not far from the arts and culture attraction and will round out your day nicely.
