The oldest extant house associated with the prominent Dorsey family, Belmont is distinguished by Chesapeake-influenced architectural elements including a one-and-a-half-story configuration, clipped gable roof with paired end chimneys, and interior wood paneling. The main block was erected for Caleb Dorsey Jr. on property passed down through generations and with money generated by the Elkridge Furnace he established in 1755. Built of Flemish-bond brick and measuring 50 × 24 feet, Dorsey’s house was an imposing dwelling for its day. The hyphens and wings were configured c. 1798, and the rough-cast facing then fashionable applied c. 1815. The house was brought into the modern era in 1917, adding a new kitchen wing and expanding the hyphens. The property encompasses terracing, boxwood gardens, and outbuildings including a c. 1850 stone bank barn. Now owned by Howard County, Belmont is used as an event venue.
