Dorchester Heights
Dorchester Heights marks the site of the 1776 Evacuation of Boston, considered the first major victory of the American forces during the Revolutionary War. The significance of the site was recognized with a small monument to Henry Knox in 1876 as part of the centennial of the American Revolution. Over the next quarter century, as Boston began to celebrate Evacuation Day, a movement for a more substantial monument resulted in an architectural competition and the construction of a tower designed by Peabody & Stearns which was dedicated in 1902.
Years of severe deterioration had restricted access to both the Monument and major portions of the landscape, limiting the public’s ability to enjoy a site that serves as both a South Boston gathering place and a cornerstone of America’s Revolutionary story. By the early 2010s the National Park Service recognized issues with both the site hardscape and the Monument itself and began a design effort which resulted in the creation of a comprehensive project funded under the Great American Outdoors Act.
Stantec, SmithGroup, and Building Conservation Associates led a full restoration of the monument and its surrounding landscape. The project involved skill, planning, and craftsmanship to restore the monument’s marble elements. Each marble block at the tower’s summit was carefully disassembled, meticulously cataloged, and individually assessed by expert stonemasons. Marble from the original quarry was secured to ensure the restored Monument retains its historic character. The entire site was re-graded to provide an accessible route to the monument. The work was completed in the summer of 2025, and the site was rededicated on March 17, 2026, as part of the 250th anniversary of the evacuation of Boston.
The result is a fully renewed site that enhances community vibrancy and strengthens Boston’s storytelling landscape. The reopened Monument interior and newly accessible pathways invite residents and visitors alike to experience the Heights in ways that have not been possible for decades. By seamlessly combining preservation excellence with improved public access, the project restores an iconic symbol of Boston’s Revolutionary heritage and renews its role as a cherished, active, and inspiring public place.
