They were found in a sunken ship three centuries ago – but just now going on display.

Argentine officials are showing off relics recovered from a Spanish ship that sank off the South American coast in the latter half of the 18th century.

There are military cannon, pieces of rare silver and old pottery, as well as remains of the merchant ship itself among the 15,000 items on display in Buenos Aires.

The ship foundered just off the coast centuries ago and was gradually overtaken and buried by sediments.

Workers recovered the ruins in 2008 and 2009 after finding them during excavation work for a building in the Puerto Madero district.
