Built in 1677, the gambrel-roofed Harlow Old Fort House is one of the few remaining 17th century buildings in the oldest established town in the Commonwealth. It was originally the family residence of settler William Harlow, a farmer, cooper and town official, who also served as sergeant of the local militia and participated in King Philip's War. In 1676, Harlow was granted permission to salvage material from the Pilgrim's fort-house on Burial Hill to use in the construction of his new dwelling. From the early 19th century, the Harlow House has been notable for the hand-hewn beams attributed to this source.
