Hyde Park, Boston’s Last Annexation: Mills, Rivers and the 54th Regiment

Hyde Park sits at Boston’s southern tip, bordered by the Neponset River and large stretches of conservation land. It feels a little separate from the rest of the city, and for good reason. It was the last town to join Boston, and it kept its own identity long after.

A town built on water power

Hyde Park was incorporated as a town in 1868 from parts of Dorchester, Dedham and Milton. The Neponset River and its tributaries had powered mills in the area since the colonial era. One nearby waterway, Mother Brook, was dug in the 1630s to divert water from the Charles River to the Neponset, and it is often cited as the first man-made canal in North America.

The new town grew quickly in the late 1800s. Railroad lines made it possible to commute to Boston, and factories along the river produced everything from paper to machinery. The streets of Cleary Square and Logan Square reflect that era of steady small-town growth.

Camp Meigs and the 54th Massachusetts

Before Hyde Park was a town, the area known as Readville hosted Camp Meigs, a Union Army training ground during the Civil War. It was there that the 54th Massachusetts Infantry, one of the first Black regiments raised in the North, trained in 1863 before marching through Boston on its way to South Carolina. The 55th Massachusetts and the 5th Massachusetts Cavalry, also Black units, trained there as well.

A small park at the former camp site marks this history, and a memorial there honors the soldiers who trained at Readville.

Joining Boston

Hyde Park voters agreed to annexation, and the town became part of Boston in 1912. It was the final addition to the city’s land area through annexation, completing the map of neighborhoods we know today.

Green space at the edge of the city

Hyde Park has more open land than many Boston neighborhoods:

• Stony Brook Reservation, a large state-run forest with trails, ponds and a skating rink.
• The Neponset River, with river paths and spots for paddling in warmer months.
• Fairmount Hill, a residential area with Victorian homes on winding streets.
• The Boston edge of the Blue Hills, which rise just beyond the city line.

Hyde Park today

The neighborhood is largely residential, with single-family homes, two-families and a lively main street around Cleary Square. Families with Irish, Italian, Black, Haitian, Latino and many other backgrounds live here. Commuter rail stations on the Fairmount Line and other routes connect it to downtown.

On a cold weekend, take a walk through Stony Brook Reservation, where snowy trails make the city feel far away, then warm up at a cafe in Cleary Square.
