Revolutionary Harbor Lectures: 250 Years Later – The Siege and Its Impacts on Boston’s Harbor Front Communities
Revolutionary Harbor Lectures: 250 Years Later – The Siege and Its Impacts on Boston’s Harbor Front Communities

Come learn about the siege and its impacts on the harbor front communities of Boston!

This program is presented by the National Park Service and Boston Harbor Now as a part of our three-part Revolutionary Harbor lecture series.

Following the battles at Lexington and Concord on April 19, 1775, Boston became the center of a quickly developing war between rebelling colonists and the forces of the British government. Colonial militia from Massachusetts, Connecticut, New Hampshire, and Rhode Island formed an Army of New England to surround and contain the British forces occupying Boston. Over the course of the next 11 months, both sides engaged in what became known as the Siege of Boston. Join the National Park Service’s Savannah Rose as she explores the impact of the Siege on Boston’s harbor front communities and the city’s collective memory and memorialization of those historic months.

Location: Atlantic Wharf (Fort Point Room) 290 Congress Street Boston, MA 02210

Date: Feb 19, 2026 12:00am to Feb 19, 2026 12:00am
