In the late 18th century, the Palazzo Mirto was built on what was once the foundation of a building dating from the 13th century. The palace was built for a wealthy family as their residence, which is exactly what it was until 1982. At that point, the family that lived there - the Lanza Filangieri family, princes of the nearby town of Mirto - gave the palace to the government of Sicily.
Today, the Palazzo Mirto is kept in the fashion of an 18th or 19th century aristocrat’s home. Many of the palace’s rooms are decorated with furniture and artwork that was originally owned by the Lanza Filangieri family, so in some cases these pieces have occupied the Palazzo Mirto for centuries.
