The Pantheon of Illustrious Sailors (Spanish: Panteón de Marinos Ilustres) is a mausoleum and memorial to all the mariners of the Spanish Navy, especially prominent ones, and to the Spanish Navy and all its ships, battles and explorations in general. The term Pantheon is a concession to the generally prevalent and popular style of neoclassical architecture, which is supposed to have begun explicitly in the 18th century, but was in use long before then in the Renaissance, a "rebirth" of classical civilization, especially in decorative ornamentation.
