Protect the Harbor!

Fort Jay and Castle Williams, the two historic forts that make up Governors Island National Monument, were built to protect New York City from naval attack. The online game "Protect the Harbor" (part of the WebRangers program) is a fun way to teach students about the War of 1812, and test how well they can defend a coastal city like New York! They will also discover where other forts in New York Harbor were located, and why this system was so important to the brand new United States.
