During the late 19th century, a network of pedestrian paths and walks was constructed in Brookline to facilitate the passage of citizens up and down Corey and Aspinwall Hills to the new Beacon Street Boulevard where there was a streetcar line. Beacon Street, widened in 1887 according to plans drawn up by Frederick Law Olmsted, afforded such easy access to Boston that mansions were built for wealthy families abutting the stylish street. On this walking tour of the paths, your guide from Brookline Adult and Community Education will cover all the stairs and terraces that comprise the great circuit of pedestrian walks, from Summit Path all the way to Beaconsfield Path ending at the MBTA Beaconsfield station. The history of the paths and the surrounding architecture, and the story of the lost paths will be recounted. This is a long, strenuous walk that covers several miles of primarily stairs, but participants may drop out at any point along the way and hop onto the Green Line to return home. Please wear comfortable walking shoes and bring a bottle of water. Call 617-730-2700 to register. Fee is $25, plus a $6 registration fee if you have not registered for another course with Brookline Adult Ed this semester. Meet at the intersection of Washington Street and Beacon Street in Brookline. Register on-line if you wish at www.brooklineadulted.org.
