An ancient walled city set on the banks of the River Foyle, Londonderry is one of the oldest continuously inhabited places in Ireland. Its nickname, the Maiden City comes from the fact that its city walls were never penetrated during the siege of Derry in the late 17th century. The River Foyle forms a deep valley as it flows through the city, making Londonderry a place of very steep streets and sudden, striking views. The city is a major shopping district, housing two large shopping centres and numerous shopping avenues. It is also home to Austins - the world's oldest independent department store, housed in a five-story Edwardian building in the city centre. Here a large collection of late Georgian, Victorian and Edwardian buildings gives Londonderry a distinct character. The city's nightlife is mainly centred along Waterloo Street where live rock and traditional music can frequently be heard emanating from the pub-doors. The city is renowned for producing exceptionally talented musicians and many bands perform in venues around the city. There are many museums and sites of interest in and around the city.
