Portara, a huge marble gate and the single remaining part of an unfinished temple of Apollo of 530 BC, is Naxos’s emblem and main landmark. Standing on the islet of Palatia, at the entrance to Naxos harbor, it comprises four marble parts weighing about 20 tons each. Its construction was initiated by the tyrant Lygdamis in the 6th century BC, according to the specifications of the temples of Olympic Zeus in Athens and of the goddess Hera on Samos. Portara today is connected with the Naxos mainland via a paved footpath.
