Gediminas Avenue (Lithuanian: Gedimino prospektas) is the main street of Vilnius, where most of the governmental institutions of Lithuania are concentrated, including the government, parliament, Constitutional Court and ministries.
Named after the Grand Duke of Lithuania Gediminas, the street terminates at the Žvėrynas Bridge over the Neris River near Seimas Palace on one end and at the Cathedral Square and Vilnius Castle Complex on the other, passing Lukiškės Square where the Museum of Occupations and Freedom Fights is located in the former KGB building.
In the Soviet period the avenue was used for demonstrations and military parades in honor of International Workers' Day on 1 May and the October Revolution on 7 November.
A portion of the avenue from the Vilnius Cathedral to Vincas Kudirka Square was thoroughly reconstructed before the celebration of the 750th anniversary of Mindaugas' coronation in 2003.
The reconstructions included building an underground parking facility – the first such in Lithuania - under the Municipality Square and renovation of all kinds of pipelines and communication cables under the street.
