Panama Viejo, located on the Pacific Ocean coast and adjacent to tthe delta of the Abajo river, is the most important archaeological site in the Republic of Panama.
It is the oldest Spanish settlement on the Pacific coast of the Americas. Founded in 1519 by Pedrarias Dávila, it was abandoned after the attack of the city by the pirate Henry Morgan and never rebuilt. Its ruins were left untouched over two centuries. Older remains, dating up to 1,000 years before the arrival of the Spanish conquistadores have also been excavated on this site (the oldest C14 date obtained until now is 500 DC). The site has been recently inscribe on UNESCO’s World Heritage List (2003).
