The Castello Secco Suardo is made up of a group of structures built around a central rectangular courtyard. The grand entryway is on the western façade, which faces the gardens (redesigned in the late 18th century as a botanical garden, including several rare and valuable species of trees and plants) and a fifteenth-century family chapel.
The building complex was originally a small farming town, with walls erected in the thirteenth century. After passing through numerous hands, the Castello became the property of the Secco-Suardo family in the fifteenth century.
Today the Castello remains their family residence and the headquarters of the Giovanni Secco Suardo Association along with its library, study center and database library of the national archive of Italian art restoration, and of the Committee for the Castello di Lurano, which leads field trips for elementary school students and educational workshops for secondary schools, concerts, and cultural events. The interior of the residence also hosts receptions for weddings, christenings, baptisms, first communions, business dinners and birthday celebrations.
