Maritsa

The Maritsa or Evros (Bulgarian: Марица, Ancient Greek: Ἕβρος (Latinised as Hebrus), Modern Greek: Έβρος, Evros, Turkish: Meriç) is, with a length of 480 km, the longest river that runs solely in the interior of the Balkans. It has its origin in the Rila Mountains in Western Bulgaria, flowing southeast between the Balkan and Rhodope Mountains, past Plovdiv and Parvomay (where the Mechka & Kayaliyka River joins it) to Edirne, Turkey. East of Svilengrad, Bulgaria, the river flows eastwards, forming the border between Bulgaria (on the north bank) and Greece(on the south bank), and then between Turkey and Greece. At Edirne, the river flows through Turkish territory on both banks, then turns towards the south and forms the border between Greece on the west bank and Turkey on the east bank to the Aegean Sea. Turkey was given a small sector on the west bank opposite the city of Edirne. The river enters the Aegean Sea near Enez, where it forms a delta. The Tundzha is its chief tributary; the Arda is another one. The lower course of the Maritsa/Evros forms part of the Bulgarian-Greek border and most of the Greek-Turkish border. The upper Maritsa valley is a principal east-west route in Bulgaria. The unnavigable river is used for power production and irrigation.

The places that the river flows through include Pazardzhik, Plovdiv, (next to) Parvomay, through Dimitrovgrad and Svilengrad in Bulgaria, Edirne in Turkey and Kastanies, Pythio, Didymoteicho and Lavara in Greece. There are a number of bridges over the river, including the one at Svilengrad, the one west of Edirne in Turkey and GR-2 with the D110/E90 further south and as its border crossings.
