Anyone interested in Patrick O'Brian's painstakingly detailed naval novels or in old vessels and war ships will be interested in the 500 years of Spanish naval history displayed in this museum. The collection, which includes documents, maps, weaponry, paintings, and hundreds of ship models of different sizes, is best enjoyed by those who speak some Spanish. Beginning with Queen Isabella and King Ferdinand's reign and the expeditions led by Christopher Columbus and the conquistadors, exhibits also reveal how Spain built a naval empire that battled Turkish, Algerian, French, Portuguese, and English armies and commanded the oceans and the shipping routes for a century and a half. Moving to the present day, the museum covers Spain's more recent shipyard and naval construction accomplishments. Guided tours, in Spanish only, are offered on Thursday at 11:15 and weekends at 11:30.
