Own a piece of Concord’s history with SCENIC LAND and RIVERBANKS seemingly untouched since the days when Thoreau described them in his journals. This 24 ACRE FARM runs along the banks of the Sudbury River with 850 FT OF RIVERFRONT and a BOAT LAUNCH surrounded by hundreds of protected acres stretching to Walden Pond. GRAND, HISTORIC, and ROMANTIC, the property preserves what is most authentic in SHINGLE-STYLE ARCHITECTURE in a pristine,19th century landscape. The combination of proximity to river frontage and conservation land, with easy access to Route 2 and the commuter rail in Concord center, makes this property a UNIQUE and HIGHLY DESIRABLE offering.
