Located in the historic Ferrol Arsenal, known as "Presidio de San Campio", built in the second half of the eighteenth century, the building that houses the Museum is already an architectural jewel of Baroque-Neoclassical style, worthy of admiration in its own right. Located within the Navy's "Herrerías Centre" complex, access to the museum is from Cantón de Molíns.

Among its resources, the Museum has more than 2,650 catalogued records, including sets and collections of historical, artistic and technical value related to the activity of the Navy, its intimate relationship with Ferrol, and the naval and maritime history of Spain.
