During the Revolutionary War, the Roxbury Highlands figured prominently in the Siege of Boston. In 1775, the colonists built major fortifications here known as the Lower Fort and High, or Upper, Fort. The two forts commanded strategic views of and access to both Boston Neck and the road between Boston and Dedham, where the rebels kept a depot of army supplies. The Lower Fort encompassed two acres of land in Roxbury between (now) Cedar, Highland, and Linwood Streets. The High Fort was located a short distance to the south and is today part of Highland Park. These were not highly fortified structures but reinforced earthen berms built on top of the natural rocky ledges of Roxbury puddingstone. (Kittredge House Report –Landmarks Commission)
