The Dana Lighthouse standing at the mouth of the Poros channel was built in 1870 by the French Society of Ottoman Lighthouses. It is one of the prettiest stone-built square lighthouses in Greece and a monument of modern maritime history. The lighthouse rises to nine meters and its focal length reaches 32 meters.
In 2011, the Aikaterini Laskaridis Foundation completed a total restoration of the lighthouse which is now also a cultural beacon of Greece’s maritime heritage.
The lighthouse is less than six kilometers from Poros Town and can be reached over a footpath off the main road after a 15-minute hike. It is a perfect viewing point over the Saronic Gulf and the Methana peninsula.
