The Tripoli Monument is the oldest military monument in the United States. It honors heroes of the First Barbary War: Master Commandant Richard Somers, Lieutenant James Caldwell, James Decatur (brother of Stephen Decatur), Henry Wadsworth, Joseph Israel, and John Dorsey. It was carved in Livorno, Italy in 1806 and brought to the United States as ballast on board the USS "Constitution". From its original installation in the Washington Navy Yard in 1808 it was moved to the west terrace of the United States Capitol in 1831, and finally to the United States Naval Academy in Annapolis, Maryland in 1860.
