The Colburn School-High Street Historic District is a linear historic district encompassing the village center of Westwood, Massachusetts. It extends along High Street (Massachusetts Route 109) roughly between Conant Street in the north and Gay Street in the south. It is largely residential in character, with 37 houses, most of which date from the 18th to the mid-19th centuries. The rural character of the area is captured by a number of preserved 19th-century barns. The district also includes Westwood Town Hall, a 1910 Classical Revival building, and the 1874 Second Empire Colburn School.
