About Spetses Lighthouse

The Spetses lighthouse, built in 1885, is a 10-meter tall, two-stage cylindrical stone tower with green trim. Its lantern and gallery sit atop the old-style masonry structure.

The focal height of the light is 27 meters above sea level, providing a geographic range of 14.7 nautical miles.
