Ex-voto of Admiral Marquês de Nisa

Ex-voto in the form of a reliquary in ebony wood, glass
door with silver clasps and hinges. Inside there is a model
of the Nau "Queen of Portugal", the head ship of the
Portuguese squadron. And, at the bottom, on parchment, the vote of the crews
of the ships of the Royal Navy to Our Lady of Navigators.
