The World War I Naval Monument at Gibraltar is located at the Straits of Gibraltar, the gateway to the Mediterranean Sea. It is a masonry archway which leads to a British Commonwealth War Graves Commission Cemetery. Over the arch are two bronze seals of the United States and the Department of the Navy. This monument, constructed of the stone from the neighboring "Rock," commemorates the achievements of the United States Navy in the nearby waters and its comradeship with the British Royal Navy during World War I.

From this monument, located in the midst of its historic surroundings, there is a flight of steps which connects the British naval establishments below with the cemetery and the picturesque town above. Gibraltar is a port of call for many ships. A visit to the monument requires about half an hour from your arrival at Gibraltar.
