Ruinas del Portus Illicitanus

Step back 2,000 years at these remarkably preserved ruins of the ancient Roman port that once connected this coastline to the wider empire. Dating to the 1st century AD, Portus Illicitanus was a bustling hub of trade and commerce, and you can still make out the structural remains that ancient geographers actually wrote about. It's a rare chance to stand on ground that was genuinely significant in the Roman world, not just a roadside footnote.
