The Galleria Nazionale d'Arte Antica is located in the grand Baroque palace known as Palazzo Corsini. This famous building has witnessed many important moments in history.
Palazzo Corsini gained special recognition when Christina, Queen of Sweden, made the palace her home during the final years of her life. After abdicating the throne, she moved to Rome, bringing her love for art and culture with her. Her stay added a unique royal legacy to the already impressive history of the palace.
