The National Museum of Subaquatic Archaeology (Museo Nacional de Arqueología Subacuática - ARQVA) in Cartagena is an underwater archaeology museum. It owns a large collection of pieces recovered from shipwrecks that begins in the Phoenician period, and arrives until the 19th century.
On December 2, 2012, the 14.5 tons cargo of gold and silver coins recovered from the wreck of the frigate Nuestra Señora de las Mercedes was deposited in the museum for cataloging, study and permanent display.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
