Chania Lighthouse, Stone lighthouse in Chania, Greece.

The Chania Lighthouse is a stone masonry tower rising 26 metres above the bay at the entrance of Chania's port. Only the base of the original Venetian structure remains; the tower was rebuilt in 1864. At the top, a gallery holds a light that flashes red every 2.5 seconds, visible up to 7 nautical miles.

The Venetians built a naval post here to guard the city against Turks and pirates; it fell into ruins after the Ottoman capture of Chania in 1645. Egyptian troops serving the Ottoman Empire rebuilt the lighthouse in 1864, leaving only the base of the original structure. A fixed white light was installed in May 1915, and the tower was refurbished in 2006 after World War II damage.

The lighthouse is known locally as Kolpos Khanion, literally "bay of Chania", a name it shares with the waters it marks. Its red flash every 2.5 seconds, visible up to 7 nautical miles, is the signal Cretan fishermen and ferry crews watch for when entering the old port.

The beacon stands at the harbor pier's end with the Firkas fortress nearby, making it easy to locate. Visitors walking to this spot can take in views of the Cretan Sea and the entire harbor basin from its surroundings.

Only the base of the original Venetian structure survives; the rest of the tower dates from the 1864 Egyptian rebuild. The light was automated and now flashes red every 2.5 seconds, visible 7 nautical miles (13 km) out to sea. It has been a listed archaeological site since 1962.
