The lighthouse of Possidi in Halkidiki: At the end of Possidi beach stands a charming old whitewashed lighthouse. Built in 1864, the lighthouse stood very near to the water in its early days but now the sea has backed away. The sand stretch was formed later from piling up of sediments. This colonial-styled lighthouse is still in use today and has a small flowery garden beside it, adding to its beauty.
Tall pine trees line behind the traditional lighthouse which sits solemnly on the edge of the beach. It is the only building along the beach of Possidi. Near the lighthouse lie the ruins of the ancient temple of Poseidon, while 1 km to the west, the beautiful church of the Virgin Mary is found, built in 1619.
