    Centuries old European world meets modern day amenities in this extraordinary 10 acre Potomac estate. You must see this property if: you desire to land your helicopter in your yard; entertain large gatherings - whether it be for weddings, fine arts displays or performances; host concert pianist recitals; house guests who travel for your venue or to be close to an event in Washington DC; you represent an institution searching for a satellite location for gatherings to further education or to enrich experiences through group meetings and presentations; you want to host brainstorming conventions with colleagues; you are involved with a government embassy seeking a serene setting close to DC; you are looking for a tranquil, inspiring haven to host retreats or ceremonial gatherings; perhaps you would simply like to bring your horses home; fish in your own carp filled pond; you are an artist looking for inspiration and a studio to display your creations; you are a writer seeking inspiration and an escape from the hustle & bustle of city living but do not have the time to travel to Europe ; you may want to swim laps year round in your "against the current" indoor pool (which has a specially designed HVAC system to reduce humidity) or enjoy a game of pool volleyball with your family and friends; you may enjoy cooking in the true gourmet kitchen boasting a spectacular Lacanche stove imported from France; you may just want a gracious home that your family can enjoy. So, if you are one who appreciates all of the amenities offered at this grand property and respects the integrity of the craftmanship, resources, labor and research that curated to recreate the appearance of centuries old, Medieval, old world European influenced architecture and culture, then this glorious home is for you! Enter "Albero del Segnale" upon the driveway built of centuries old repurposed cobblestones that came to this country from Europe as ballasts on sailing ships and were then used to pave city streets. Pass through the iron gates, the double stone entrance pillars capped with custom made lanterns from Italy and along the driveway lined with antique streetlamps. Greeted by the front landing made of hand-hewn antique limestone pavers from Italy and twin Corinthian limestone columns also custom made in Italy. The front doors, supported by gold-plated, hand-chiseled hinges custom made in France, are a spectacular classic Italian design featuring iron grillwork in the glass transoms and a working "man door," or a door within a door whose tradition dates to Medieval times. The grand foyer drenched with natural light from 2 story windows has welcomed many renown performers and pianists as the open flowing floorplan offers the perfect venue for performances, not to mention the acoustics are fantastic. Every room in this grand, glorious home is abundant with natural light as every angle of each room has magnificent windows connecting the pastural rolling outside views with the interior. Centuries-old hand-molded antique terra cotta floors, in which imprints of the artisan's fingers and hands as well as occasional animal footprints are forever defined as they were imprinted before the tiles dried and were fired. Solid iron balusters and railings custom for this home were hand forged in Italy.The flooring in the kitchen and family room is solid white oak, custom-stained using only ammonia fumes-an Old-World technique discovered in England as a result of decades of exposure of white oak barn wood to ammonia from horse urine. Solid wood, butternut, black walnut, cherry, reclaimed barn wood from historic barns and monasteries add to the charm and sophistication.Elements of old have been tastefully replicated with all of the modern amenities and comforts. Many antiques and artifacts from various countries have been integrated in the construction of this spectacular home.Every detail has been thoughtfully constructed.Comforts of modern day living abound the Old World charm.
