The building cannot currently be visited because it is private property: here the Mazzocchi Alemanni Magdalena and Maurizio commercial farm is based.
The castle must have been the noble residence of a lord of the Leoni family, as witnessed by the coat of arms standing out on the front door. The name might come from Campoleone then turned into Campi di Leone.
In 1512, nearby the building, along the route between Pontecuti and Casemasce, the well-known Nicchio di Todi, a marble aedicula from a decommissioned Roman temple, was found. Today it is enshrined in the Vatican Museums.
In 1565, Cipriano Piccolpasso passed through the region. He was the Perugia fortress superintender, in charge of surveying all the cities, fortresses and castles in the province.
Inside the building there is a small church dedicated to St. Lucia, next to a pointed-arched bell tower.
Then, in modern times, the castle passed from the Leoni to the current owners, Alemanni Mazzocchi.
