Set in the Pisan hills near Fauglia, the restored villa dates to the early 20th century and is built in the Liberty style, the Italian take on Art Nouveau.

Built at the turn of the 20th century for James E. Nichols and designed by C.P.H. Gilbert, 4 East 79th Street has lived several lives: private Gilded Age mansion, crime scene, diplomatic address, subdivided residence, and ultimately a painstakingly reconstructed single-family home.

Sport Island sits in New York’s Thousand Islands, the St. Lawrence River archipelago along the Canadian border that became one of the Gilded Age’s fashionable summer destinations. Built around 1880 for a prominent Pennsylvania railroad-industrialist family, the property has since undergone a substantial partial restoration.

The 5-bedroom farmhouse was built around a 13th-century watchtower, with views across the rolling Tuscan hills, around 30 minutes from Siena and under an hour from Florence.

Known as the “green heart of Italy,” Umbria is home to this historic Antico Borgo Rurale, where a group of old farm buildings has been restored as one private estate.

“What separates Staples Point is that its greatest assets can’t be recreated,” says listing agent Sam Michaud of Legacy Properties Sotheby’s International Realty. “The land, the frontage, the five lighthouse views, the privacy and the proximity to Portland cannot be replicated.”

A 10,800 ft² Greek Revival townhouse overlooking Washington Square Park has come to market after more than 60 years in the same family.

The property offers both scale and charming setting in a region gaining international attention for its wines and landscapes.

Set within the Sciusa Valley near Noli and Spotorno, the 3-bedroom residence occupies the villa’s piano nobile, its principal reception floor, with vaulted ceilings, 18th-century frescoes, private grounds and a swimming pool.

Perched above the surrounding vineyards, this rose-coloured French bastide takes in broad views across the Provençal coast near Cassis, a historic fishing port on the French Riviera about 30 minutes east of Marseille.
