As the world’s premier luxury real estate marketplace, Sotheby’s Concierge Auctions is no stranger to representing exceptional properties. Notably, the firm recently successfully auctioned ‘La Dune’’ on famed Gin Lane in Southampton at Sotheby’s New York for a record-breaking US$88.48 million in January 2024.

Headlining the upcoming sale are a 65± acre equestrian estate in Valle de Bravo, Mexico; an expansive, 34,000-square-foot, 200-acre circa 1927 castle in upstate New York with sweeping Catskills views; a magnificent Tuscan-style residence located in Potomac, Maryland; a seaside villa on Greece’s famed Mykonos Island; and a historic Italian wine vineyard in the foothills of the Piedmont Mountains.

‘Rancho El Salto’ in Valle de Bravo, Mexico is an expansive 65.48-acre ranch and estate in a nature-filled oasis in Mexico’s famed Valle de Bravo. Located in a gorgeous lakeside town along the shore of the popular water sports destination Lake Valle de Bravo and near a diverse natural landscape including rivers, lakes, waterfalls and bountiful forestry, the residence is a prime choice for nature and equestrian lovers.

In addition to its nearby environment, ‘Rancho El Salto’ offers facilities such as a swimming pool, jacuzzi, swim lane, soccer field, paddle tennis court, horse-riding arena, fully-equipped stable, golf green with nine tees at different distances, and a greenhouse. The country house, tinged with Italian Tuscany accents throughout, spans 19,375 square feet and offers seven bedrooms, seven full bathrooms, and four partial bathrooms.

Migdale Castle, located at 3872-3874 Route 44 in the Village of Millbrook, New York, is one of the Hudson Valley’s most iconic properties. Sitting on 200 acres of land that are broken into two parcels—one 50-acre piece, and an adjacent 150-acre piece, available for separate sales or together as a unit—the home exists as an expansive four-story residence that occupies 34,000 square feet and encompasses 29 rooms, 10 bedrooms, 12 full baths, six half baths, and 12 fireplaces, 5,000-bottle wine cellar, a 13-seat media room, an athletic room, a golf simulator, and an elevator. A winding private driveway marks the entrance to the property, leading to a renovated 5,000 square-foot gatehouse and opening up to sweeping vistas of over 100 acres of meticulously manicured lawns and beautiful gardens, as well as stunning views of the Catskill Mountains.

The residence has a storied past. Its cornerstone was laid in 1927 by the daughter of Andrew Carnegie, who aimed to evoke the grandeur of another famous Carnegie property, Skibo Castle in Scotland. Acquired by its present owners in 2000, they embarked on a four-year renovation project, expanding the property with an additional 100-acre lot to its existing 200 acres, resulting in the unveiling of one of Millbrook’s premier and most expansive estates.

Listed at US$14 million, the property is being offered in cooperation with co-listing agent Heather Croner of Heather Croner Real Estate Sotheby’s International Realty. Bidding is estimated to start between US$4 million and US$8 million.

‘Albero del Segnale’ is a magnificent Tuscan-style residence located in Potomac, Maryland. Located at 13320 Signal Tree Lane, the property’s historic charm permeates its design, with vintage and reclaimed materials lending authenticity to its ambiance. The journey begins with a driveway paved with centuries-old cobblestones, originally used as ballast on European sailing ships before gracing the streets of cities. Flanked by imposing Corinthian limestone pillars adorned with custom Italian lanterns, the driveway leads to a sprawling cobblestone piazza unveiling the home’s stone and stucco exterior, crowned with multi-colored roof tiles reminiscent of a small Italian hillside town. Noteworthy is the presence of a bell tower housing a 300-lb bronze bell.

Encompassing 26,698 square feet, the estate boasts six bedrooms, 10 full bathrooms, and four half baths, all exuding a historic Tuscan ambiance.

At nearly 10 acres, ‘Albero del Segnale,’ or ‘Signal Tree,’ in English, derives its name from its Civil War heritage, where an old chestnut tree on the property was used by Union troops as a signal relay station. From the top of the tree, troops were afforded a direct line of sight both to the U.S. Capitol and to Maryland Heights, just across the Potomac River from Harper’s Ferry. ‘The Signal Tree’ is famously illustrated in an 1866 issue of Harper’s Monthly Magazine, depicting the tree, stripped of foliage, and outfitted in a series of ladders and platforms, where troops would be situated at the top of the tree to relay signals in both directions. In more recent years, construction teams inadvertently excavated an area where the blacksmith tent had stood a century-and-a-half earlier, uncovering a large horseshoe and a block of blacksmith coal.

The current owners are the esteemed Dr. Gregory Prince, a distinguished virologist, entrepreneur, and author, alongside his wife, JaLynn Prince, a philanthropist and entrepreneur. The two have cherished the residence as the keystone of their family, where they raised their three children.

Listed at US$11.5 million, the property is being offered in cooperation with Peg Mancuso of TTR Sotheby’s International Realty. Bidding is estimated to start between US$3 million and US$6 million.
