Executive Summary
Built in 1861, Building 43 is one of the oldest in the Arsenal on the Charles, and was a part of the original Seacoast Gun Carriage Complex. The building was one story high, 300 feet long and 56 feet wide. It was equipped with machines to forge the cast iron components for the carriages of large seacoast cannons designed by the Arsenal’s commanding officer, Thomas Rodman.
During WWI, a second story addition was built to house new equipment to construct even larger components for 14- and 16-inch seacoast gun carriages. Operators used two and three-and-a-half ton steam hammers to forge steel castings as large as 8,000 pounds. After World War II, Building 43 supported the Arsenal’s ongoing research activities with experimental and specialty forgings. It is one of the only buildings to retain its original use throughout the arsenal’s history.
