Portland Head has long protected Portland and the adjacent area. Cape Elizabeth residents were deeply committed to American independence from British rule. In 1776, the new Town of Cape Elizabeth posted a guard of eight soldiers at Portland Head to warn citizens of coming British attacks. In 1787, the General Court of Massachusetts (the Massachusetts legislature) provided $750 to begin construction of a lighthouse. In 1790, when the United States Government took over the responsibility of all lighthouses, Congress appropriated $1,500 for its completion. The original tower measured 72' from base to lantern deck and was lit with 16 whale oil lamps. It was first lit on January 10, 1791.
