It was initiated at the request of Count Alessandro Pianciani to celebrate his marriage with Costanza Collicola, a member of a noble family of Spoleto.

The Secret Garden, a large elliptic esplanade in front of the facade, is encircled by a two-wall portico that opens to two opposite, open-sided galleries with panoramic views and two vast symmetrical Gazebos (pavilions) in wrought iron decorated with roses.

The geometric and symmetric character of the layout adheres to traditional Italian gardens, combining decorative elements, comfort, and nature.

The main house is typical of the Roman baroque style of French contemporary buildings at the time the Villa was built.

The decorative elements are mainly handworks by unknown craftsmen, dating back to the years following the construction until the first decade of the 19th century.

The triangular tympanum, the four columned doric porch, the symmetric structure of the barrel-vaulted isle, and the two lateral sacristies show strong ties to Palladian architecture.

Designed by Valadier as an entity that unites with the rest of the Villa, the Secret Garden is composed of an elliptic wall, cobbled stairs, a shrine arch and the remains of a fountain and a sundial.

This building, more linear than the Main House, is on the northwest side of the hill and offers a magnificent view of the valley in the direction of Montefalco and Assisi.

The two bottom floors of the Annex follow the natural height difference of the hill and stop at the independent and spacious garden of the ‘Piazzale del Tramonto’ which can also be reached by a separate driveway (‘Viale dei Gelsi’).

[2] An additional building, recognizable today only as a ruin, represents the unique survivor of two symmetric artifacts originally set at the sides of the main avenue of entry and named barracks’.

Across from the entrance surrounded by oaks, is a 2000 m2 park where cypress trees lead to the peak of the hill with two lateral paths that guide the way along the property.

The layout is in the geometric and symmetric lines of traditional Italian gardens, while the park as a whole follows the contour of the land in the style of English naturalism with hundreds of box hedges that create shaded winding walkways called ‘Cocchi’, bounded by pergolas and flowers.

After the 1990s, the line of the family that inherited one part of the Villa Complex − the descendants of Matilde Pianciani − were able to buy back the other half.
