Built in 1885

Tucked along one of the most sought-after streets in West Cambridge, between Harvard Square & the Charles River, this beautifully proportioned home blends historic character with everyday convenience. Mercer Circle, originally called Telephone Street, is part of a storied enclave developed by Gardiner G. Hubbard, founder of the National Geographic Society and 1st president of Bell Telephone Company. The property showcases a 29' covered wrap-around porch overlooking specimen plantings. Inside, gracious rooms are defined by tall windows & ceilings, fireplaces, and custom built-ins. Outside, the irrigated fruit gardens yield plums, blueberries, apples, and vegetables. Ideally located just 0.2 miles from BB&N’s Lower and Middle Schools and approximately one mile from Shady Hill School & BB&N’s Upper School. Properties on Mercer Circle are rarely offered, as residents tend to stay for generations, drawn by the tranquil setting, community, & enduring curb appeal.
