Volos (Greek: Βόλος) is a coastal port city in Thessaly situated midway on the Greek mainland, about 326 kilometres (203 miles) north of Athens and 215 kilometres (134 miles) south of Thessaloniki. It is the capital of the Magnesia regional unit. Volos is the only outlet to the sea from Thessaly, the country's largest agricultural region. With a population of 144,449 (2011), it is an important industrial centre, while its port provides a bridge between Europe, the Middle East and Asia.
Volos is the newest of the Greek port cities, with a large proportion of modern buildings erected following the catastrophic earthquakes of 1955. It includes the municipal units of Volos, Nea Ionia and Iolkos, as well as smaller suburban communities. The economy of the city is based on manufacturing, trade, services and tourism. Home to the University of Thessaly, the city also offers facilities for conferences, exhibitions and major sporting, cultural and scientific events. Volos participated in the 2004 Olympic Games, and the city has since played host to other athletic events, such as the European Athletic Championships. Volos hosted the 7th International Olympiad on Astronomy and Astrophysics from 27 July to 5 August 2013.
