Mulberry Fields is one of those rare places where the land itself tells the story. The mile-long cedar avenue announces the approach, its rows planted at an ever-widening angle to draw the eye toward the Potomac below, a feat of 18th-century landscape design so precise it has appeared in gardening textbooks for centuries. At the end of that drive stands the last surviving Georgian manor house in St. Mary’s County, a ca. 1755 brick estate where the center hall, great room, and dining room are paneled in raised wood from floor to ceiling, the original moldings, doors, and mantels intact after nearly 270 years. Beyond the manor, two Georgian brick dependencies anchor a formal north courtyard, and the grounds unfold across just under 500 acres of fertile land before meeting 1,700 feet of white sand Potomac riverfront. There is simply no other property like this on the Eastern Seaboard. Property and opportunity details provided by seller or others; buyer to verify.
Mulberry Fields fait partie de ces rares endroits où la terre elle-même raconte une histoire. L’allée de cèdres, longue d’un mile, annonce l’arrivée ; ses rangées sont plantées selon un angle qui s’élargit progressivement pour attirer le regard vers le Potomac en contrebas, un chef-d’œuvre d’aménagement paysager du XVIIIe siècle si précis qu’il figure depuis des siècles dans les manuels de jardinage. Au bout de cette allée se dresse le dernier manoir géorgien encore debout du comté de St. Mary’s, une propriété en briques datant d’environ 1755 où le hall central, la grande salle et la salle à manger sont lambrissés de bois en relief du sol au plafond, les moulures, portes et cheminées d’origine étant restées intactes après près de 270 ans. Au-delà du manoir, deux dépendances géorgiennes en briques encadrent une cour nord formelle, et le domaine s’étend sur un peu moins de 500 acres de terres fertiles avant de rejoindre les 1 700 pieds de rive de sable blanc du Potomac. Il n’existe tout simplement aucune autre propriété de ce genre sur la côte Est.
Mulberry Fields es uno de esos lugares excepcionales en los que la propia tierra cuenta la historia. La avenida de cedros, de una milla de longitud, anuncia la llegada; sus hileras están plantadas en un ángulo cada vez más amplio para dirigir la mirada hacia el Potomac, que discurre más abajo, una proeza del diseño paisajístico del siglo XVIII tan precisa que ha aparecido en los libros de texto de jardinería durante siglos. Al final de ese camino se alza la última casa solariega de estilo georgiano que se conserva en el condado de St. Mary’s, una finca de ladrillo de alrededor de 1755 en la que el vestíbulo central, el salón principal y el comedor están revestidos de madera en relieve desde el suelo hasta el techo, con las molduras, puertas y repisas de chimenea originales intactas tras casi 270 años. Más allá de la mansión, dos dependencias georgianas de ladrillo enmarcan un patio norte formal, y los terrenos se extienden a lo largo de algo menos de 500 acres de tierra fértil antes de llegar a los 1.700 pies de costa de arena blanca a orillas del río Potomac. Simplemente no hay ninguna otra propiedad como esta en la costa este.
Mulberry Fields è uno di quei rari luoghi in cui è la terra stessa a raccontare la storia. Il viale di cedri lungo un miglio ne annuncia l’avvicinarsi, con i suoi filari piantati secondo un angolo che si allarga progressivamente per attirare lo sguardo verso il Potomac sottostante: un capolavoro di progettazione paesaggistica del XVIII secolo talmente preciso da essere citato nei manuali di giardinaggio da secoli. Alla fine di quel viale si erge l’ultima dimora signorile in stile georgiano sopravvissuta nella contea di St. Mary’s, una tenuta in mattoni risalente al 1755 circa, dove il salone centrale, il grande salone e la sala da pranzo sono rivestiti con pannelli in legno a rilievo dal pavimento al soffitto, con modanature, porte e mensole del camino originali ancora intatte dopo quasi 270 anni. Oltre la tenuta, due annessi georgiani in mattoni delimitano un cortile formale a nord, e il parco si estende su poco meno di 500 acri di terreno fertile prima di incontrare i 1.700 piedi di riva sabbiosa del fiume Potomac. Non esiste semplicemente nessun’altra proprietà come questa sulla costa orientale.
“桑树田”(Mulberry Fields)是那种罕见的、土地本身就能讲述故事的地方。一条长达一英里的雪松林荫道昭示着此处的到来,林荫道上的雪松以逐渐扩大的角度成行种植,将视线引向下方的波托马克河——这是18世纪景观设计的一大杰作,其精确程度之高,数百年间一直被收录于园艺教科书中。在这条林荫道尽头,矗立着圣玛丽县现存的最后一座乔治亚风格庄园宅邸。这座建于约1755年的砖砌庄园中,中央大厅、大客厅和餐厅从地板到天花板均铺设着浮雕木饰面板,历经近270年岁月,原始的装饰线条、门扇和壁炉架依然完好无损。庄园之外,两座乔治亚风格的砖砌附属建筑构成了北侧正式庭院的核心,庄园占地近500英亩肥沃土地,向外延伸,最终与1,700英尺长的波托马克河白色沙滩河岸相接。在美国东海岸,根本找不到第二处像这样的房产。

Mulberry Fields traces its origins to a 25-acre deed of 1755, the earliest known reference to the property by name, making it the oldest documented estate of its kind in St. Mary’s County and the last surviving Georgian manor house in the county today. The house was likely built by John Attaway Clarke, who purchased the tract from Samuel Johnson that year; upon Clarke’s death in 1779, the property passed to his nephew, William Somerville, under whose tenure the plantation reached its peak prosperity around 1800. Somerville expanded his holdings to 10,000 acres along the Potomac and is documented as owning an early patent cotton gin and a fabric mill. After his death in 1806, the estate passed to his son, William Clarke Somerville, an Army Major in the War of 1812 who subsequently made the grand tour of Europe, befriending Lord Byron, the Duke of Wellington, Lucien Bonaparte, and the Marquis de Lafayette, and who went on to purchase Stratford Hall, birthplace of Robert E. Lee, directly across the Potomac. He rechristened Mulberry Fields “Montalbano” upon returning from Italy, though the name never stuck after he sold the plantation in 1822. The property changed hands several times before Thomas Loker acquired it in 1832 and added the two-story Doric portico, whose columns were turned on a gun lathe in Washington, D.C. and floated down the Potomac. The estate was added to the National Register of Historic Places in 1973. Maryland Historic Trust-approved renovation and addition plans convey with the sale.

St. Mary’s County occupies the southernmost tip of Maryland’s Western Shore, where the Patuxent River meets the Potomac and the pace of life reflects the landscape: unhurried, historic, and oriented toward the water. The surrounding area offers wineries, art galleries, antique dealers, and acclaimed seafood restaurants drawing on the county’s deep Chesapeake Bay heritage. Historic St. Mary’s City, the original colonial capital of Maryland, is within easy reach, as are the recreational waterways of Solomon’s Island. Washington, D.C. is approximately one hour and 15 minutes by car, making Mulberry Fields a rare opportunity to hold a genuine historic estate within reach of the capital.
