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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
