The original tower was 58'. It was built on Waltham city land and the communities of Waltham, Newton, Lexington, and Wellesley donated $900 each to fund the installation. In 1942, two-way radios were installed. In October of 1942, the tower cab burned due to a civillian aircraft spotter being careless with the tower stove. During the winter of 1942-43, the cab was rebuilt. In 1964, a new 68' steel tower (last one standing) was built. The new tower was surrounded by a chain link fence and had wire mesh over the windows. Usage of this tower was discontinued at the end of the 1977 fire season.
