On Wednesday, Grand Duchess Maria Teresa attended a private recital given by the Escolania de Montserrat Boys Choir at Berg Castle. The choir is one of the oldest in Europe since its creation dates back to the 14th century in Montserrat, a monastery 50 km northwest of Barcelona. The choir is currently in Luxembourg as they will perform at Luxembourg Cathedral on Thursday.

Grand Duchess Maria Teresa wore a Giorgio Armani jacket with a Giorgio Armani dress, a Giorgio Armani belt, and Prada pumps. She also wore Giorgio Armani earrings with her Christophe Lhote rings.
