The Lighthouse of Saint Theodoroi was named after the small church near it, and today the entire nearby area where there is beach, camping, rented houses and restaurants is called “Fanari”. The need for a lighthouse in the area was obvious in order to see the ships coast and avoid the impact on the rocks. The construction of the lighthouse was completed in 1829 by the English commander of Kefalonia, Charles Napier, with engineer J. Kennedy. It consists of 20 columns that surround a Doric circular building, while at the top there is a small tower that was the housekeeper’s house. The total height of the building is 8 meters. It is said that the Lantern owes its unusual shape to a neighboring windmill that inspired the manufacturers. After the union of the Ionian Islands in 1846, the lantern joined the lighthouse system of Greece. The original lighthouse was demolished by the earthquakes of 1953, but was rebuilt 10 years later on its original design by the Kefallonian engineer Takis Pavlatos, while in 1999 maintenance works were carried out without altering the shape of the building.

Fanari is a trademark of the Argostoli area, as apart from architectural gem, it is also a popular spot for strolling especially during the sunset, from where the visitor after passing through Katavothres can admire a wonderful sunset overlooking the peninsula the Paliki and the Vardiani Island, two uninhabited islands at the entrance of the Argostoli bay, one of which, apart from the ruins of two temples, is another modern lighthouse.
