A single path that, through trails 370, 327 and 331, connects four wonders of the Berardenga area: the farm of Catignano, once a village, already documented from the 13th century; the villa of Geggiano, whose current layout dates back to 1768 and famous because it was the home of the internationally renowned Sienese archaeologist Ranuccio Bianchi Bandinelli; the villa of Monaciano, with the adjoining farm and the splendid park decorating the building transformed around the middle of the 19th century.

Finally, the treasure chest of wonder and beauty represented by the famous Certosa of Pontignano, a place of prayer of St. Catherine of Siena, patroness of Europe, founded as a monastery in the 14th century, now a spectacular building complex rich in marvellous architectural and artistic elements, intended for receptive activities.

Trails 328, 329 and 370A make it possible to shorten the route by creating loops of smaller size and allowing, perhaps in two outings, to fully enjoy the beauty of an area rich in architectural features. Trail 370A allows a variation of the route through which it is possible to overlook the lake of the Monaciano farm.

Points of interest:

Worthy of note are the four historical and architectural places of interest which give the route its name: the Villa Ranuccio Bianchi Bandinelli in Geggiano, the Villa of Catignano, the Certosa of Pontignano and the Villa of Monaciano. Three historical residences and a religious building enriched by wonderful gardens and parks, which inside preserve furnishings and finishes of high value and historical appeal.
