Albero del Segnale is a luxurious Italian-style villa located on ten acres in the Potomac countryside on historic Civil War property. The custom-built home was meticulously crafted with reclaimed European materials, including cobblestone, limestone columns, and over 100 uniquely intricate handcrafted wood doors. The villa's design evokes a traditional Tuscan hilltop village, featuring multiple courtyards, garages, and a three-story bell tower. Inside, the home boasts exceptional details like Venetian-inspired stencils, a terra cotta entry hall, and countless European antiquities. The villa includes multiple fireplaces, a grand piano, a professional-grade kitchen, an expansive family room, a two-story library, and multiple large hosting spaces with wet bars. There are numerous luxurious spaces such as a main-level master suite with his and hers bathrooms, a reflection room called ""The Temple,""Â an indoor lap pool, and Turkish baths. The home's upper level contains five additional bedrooms, and a TV lounge. The lower level offers practical amenities, including a design studio, a rustic in-law apartment, another bedroom or staging room, several large gathering rooms perfect for lectures and/or seated dinners, along with a secure 1,600 square foot vault. The ten-acre estate also features outdoor attractions like a workshop, pond, large lighted parking area or flat green space for events, gently rolling hills of pasture grasses, an elevated garden to allow for natural irrigation, and chapel ruins. The estate is ideal for artistic retreats, film premieres, writer's gatherings, performance showcases, historical or scientific presentations, musical performances, community building events, weddings, and other inspirational gatherings. Albero del Segnale is described as perfect for creative souls-artists, musicians, historians, scientists, writers, chefs, and performers-seeking inspiration in a breathtaking, authentic, historically rich environment. This is a once-in-a-lifetime opportunity to own a piece of history that can never be replicated as many of the materials are priceless and no longer available to ever be reproduced. At almost 30,000 square feet, it is the largest home for sale in Montgomery County and is priced below the assessed value. Over the last two decades, an estimated 20,000 people have come to this estate to be inspired and inspire others. As the Civil War soldiers used its former chestnut tree to look out in the distance at both what was coming and what lay beyond, let Albero del Segnale be your Signal Tree of all that's come before you and what will go beyond you.
