The petroleum industry in Aberdeen began with the discovery of significant oil deposits in the North Sea during the mid 20th Century. Aberdeen became the centre of Europe's petroleum industry. With the largest heliport in the world and an important service ship harbour port serving oil rigs off-shore Aberdeen is often called the Oil Capital of Europe. The number of jobs created by the energy industry in and around Aberdeen has been estimated at half a million.
Aberdeen has a wide range of cultural activities, amenities and museums. The city is regularly visited by Scotland's National Arts Companies. The Aberdeen Art Gallery houses a collection of Impressionist, Victorian, Scottish and twentieth Century British paintings as well as collections of silver and glass. It also includes The Alexander Macdonald Bequest, a collection of late nineteenth century works donated by the museum's first benefactor and a constantly changing collection of contemporary work and regular visiting exhibitions.
Aberdeen is home to a host of events and festivals including the Aberdeen International Youth Festival (the world's largest arts festival for young performers), Aberdeen Jazz Festival, Rootin' Aboot (folk and roots music event based at the Lemon Tree), Triptych, and the University of Aberdeen's literature festival Word.
Aberdeen's music scene includes a variety of live music venues including pubs, clubs, and church choirs. The bars of Belmont Street are particularly known for featuring live music.
