An Extraordinary Waterfront Estate on Maryland’s Eastern Shore
Kingsbay Mansion is an unparalleled waterfront estate offering timeless Georgian architecture, gracious living spaces, and exceptional possibilities for residential, hospitality, and event use. Privately situated along Coulbourn Creek near the Chesapeake Bay, this magnificent gated property provides a rare combination of luxury, privacy, and natural beauty.
An Expansive Private Estate
Recognized as the largest private residence in Somerset County, Kingsbay Mansion encompasses approximately 13,000 square feet and is offered with two adjoining parcels totaling approximately 28.554 acres. The main residence is situated on approximately 6.28 acres, while the adjoining 22.274-acre parcel is currently used for agricultural purposes and zoned MRC. Together, the properties offer exceptional opportunities for expanded wedding and event facilities, corporate retreats, agricultural use, or simply an extraordinary degree of privacy surrounding a primary or secondary residence.

The impressive ballroom features vaulted ceilings and can accommodate approximately 150 seated guests for elegant dinners, concerts, weddings, presentations, and corporate functions. Additional formal spaces include a gracious living room with a double-width fireplace and beautifully detailed beamed and crown-molded ceiling. The Chinese Chippendale-inspired formal dining room is equally remarkable, featuring mirrored china cupboards and its own fireplace.
