The Lighthouse of Alexandroupoli is perhaps the most distinctive part of the city and the emblematic landmark on each reference to the city. The need to build the Lighthouse was imperative when the port of Alexandroupolis was a hub for all ships sailing to the Bosporus and Black Sea from the Aegean. The first lighthouse was built by a French company and operated with acetylene. Later was operated with oil and turned into electric in 1974. It has undergone alterations and improvements and the last renovation was in 2002. It has a height of 18 meters (60 feet) above the ground and 27 meters (88.6 feet) from the sea level, and emits three white flashes of light every 15 seconds. The light reaches a distance of 24 nautical miles, ie approximately 44 km.
