A beguiling landmark for the whole island, Portara is one of the first things you see as your ferry approaches the island.

This monumental marble frame measuring 6 metres by 3.5 is what’s left of a portal to an Ionic temple of Apollo, started in the 6th century BC but never finished.

It stands on the islet of Palatia, once a hill on the island’s northwest coast but now only joined to Naxos port by a causeway.
