The Sardegna Arena is a temporary football stadium in Cagliari, Sardinia, Italy. Built in 2017, it hosts Cagliari Calcio football matches from 2017–18, since Stadio Sant'Elia was closed and partially demolished in order to build a new stadium. It is intended to serve as the home stadium for Cagliari until 2021, when the construction of its planned replacement is completed. Wikipedia
