Royal castle of Sarre in the same town in the Italian region of Val d'aosta for many years was the summer residence of the Savoy dynasty. Today it turned into a Museum and opened to tourists. Special attention in it deserve a gallery of trophies and Hall of fame.

The castle was built in 1710, the year on the ruins of the fortress, the first mention of which dates back to the mid 13th century. Several times he passed from hands to hands until it was purchased by the king of Italy Vittorio Emanuele II who ordered the building was restored and was used as a hunting residence during the Royal visits to the Val d Aosta. By order of the first king of Italy in the castle were also built new stables and the tower, and inside the room were completely modified. Responsible for the furnishing of the castle was appointed overseer of Milan's Palazzo Reale.

The heir of Vittorio Emanuele II, Umberto I, was also used by Sarah Costello as a hunting residence. In the last years of his reign, he ordered a complete restoration of the interior of the castle. Just then there appeared stuffed Alpine mountain goats and deer. In the same castle stayed Queen Maria Jose, even after the fall of the monarchy. And in 1989, the year Sarah Costello became the property of the government of the Autonomous region of Val d'aosta.
