Local revelers celebrate Clean Monday with a flour war, a unique colorful flour fight marking the end of the carnival season in the port town of Galaxidi, some 200 kilometers (120 miles) west of Athens, on Monday, Feb. 23, 2015. The flour fight, on the coastal road lining Galaxidis old harbor, takes place on Clean Monday, the beginning of the 40-day Christian Lent fast that ends on Easter Sunday. Although Clean Monday ceremonies abound across Greece, the most common being kite-flying, Galaxidis flour-fight is unique, and is thought to have been influenced by similar goings-on in Sicily in the 19th century.
