Theseus, the great ingrate, abandoned Ariadne on the beach at Naxos, while she slept.
Seven hundred years later, Lygdamis, the Naxian tyrant, ordered a large temple to Apollo be built facing the harbor, but his ambitions were cut short by the Spartans. The temple remained unfinished. A further 2,500 years on, the main doorway stands. Neither pillage nor earthquakes have ever brought it down.
Some say the gate was never dismantled by looters because of its enormous weight.
We prefer to think it is Ariadne's window, from where she still looks out to sea, waiting for her lover Theseus' black-sailed ship to return.
