 Most of the housing stock in Acton Centre is Federal or Greek Revival in style, although there are some houses that have later Italianate and Queen Anne styling, and there are several Colonial Revival houses.The historic district extends along Main Street (Massachusetts Route 27) from the triangular common in the west to Nagog Hill in the east, and includes a few buildings on adjacent roadways.The common is the remnant of the town's original common, established in 1731, and houses the town's monument to the American Revolutionary War.
