The Akrotiri lighthouse has guarded the island's southwestern tail since 1892 — among Greece's oldest (French-built) and finest-set: a white tower on the last lava promontory where caldera meets open sea, the horizon an unbroken circle. It is the other end's sunset: the angle exactly opposite Oia — the sun drops and the whole caldera ignites before you, walls, islets, Oia itself a distant white dot — its audience a few cars and photographers who know, never crowds. The lighthouse itself is closed (still working today) while the scene around stays always open — the sitting rocks a natural sunset amphitheatre. Half an hour's drive from Fira through Akrotiri — pair it with the dig and Red Beach in the afternoon and close at dusk: the complete southern finale.
The French-built light still working.
Caldera and open sea unbroken.

Oia is sunset-in-architecture — the village itself part of the canvas; the lighthouse sunset-in-geography — the whole caldera burning before nearly only you. For those done with Oia's crush, or who took it by morning: the lighthouse answers — a car (or a return-agreed taxi) its condition.
