The National Parks of Boston will unveil and dedicate a replica a cannon brought to Dorchester Heights from Fort Ticonderoga during the 1776 Siege of Boston this Saturday morning at 11 a.m. The cannon will remain on permanent display, according to a press release from the National Park Service.

Following the dedication ceremony, park rangers will conduct a hands-on archaeology program to simulate the work done in the 1990s, when a 200-foot wide, star-shaped trench was uncovered. There will be a number of activities for children, including face-painting and ranger-led discussions on the site’s significance to the American Revolution.

The covert seizure of artillery from the British fort at Ticonderoga and the placement of those arms atop Dorchester Heights in March of 1776 is widely credited by historians for ousting the British from their position in Boston, where redcoat troops had been stationed since 1768.
