Restoring Bunker Hill's Fence

The Student Conservation Association Massachusetts Historic Preservation Corp (SCA HPC) has been restoring the wrought iron fence around the Bunker Hill Monument, applying a new coat of paint to bring it back to its original quality. The project began in 2023, with each subsequent year’s crew repainting one of the four sides of the fence. As of 2024, two sides have been painted, and the project is slated to be completed by 2026.

Site History

The Monument sits on Breed's Hill, the site of the Battle of Bunker Hill, one of the earliest battles of the Revolutionary War. Constructed from 1825 to 1842, the Bunker Hill Monument commemorates the soldiers who fought in the battle.[1] The park's iron fence was originally installed in 1843, followed by a new iron fence in 1870, the one that still stands today.[2]

Over time, the paint on the fence has started to deteriorate, leading to rusting and other damage. Each group of HPC crew members have begun this project by removing any paint that had begun to chip off. They use wire brushes and steel wool to scuff up the old paint, which allows the new coat of paint to stick to the fence better.

The crew then washed the fence with TSP solution, a cleaning agent, to remove the buildup of grime and dirt.

To complete the project, the crew applied an anti-rusting primer to any exposed metal or rust to prevent further rusting, followed by a topcoat of thick, black paint.
