Beacon Park is built.

Originally Riverside Park and located on the east side of lower Cambridge Street, it is initially a half-mile long track for sulky racing. Purchased by John Sawyer in 1869, it is enlarged to one-mile course and renamed Beacon Park in 1870. Buffalo Bill’s Wild West show is staged here in the 1880s. The park is subsequently purchased by Eben Jordan and Amos Marsh, by the Boston & Albany Railroad in 1890, and by the Massachusetts Turnpike Authority in 1958, which uses it as a site to offload freight from trains to trucks. It is purchased by Harvard University in 2003 and is currently being developed as its Energy Research campus.
