Local Area Information Transport links have improved significantly; with the opening of the Jubilee Line extension in 1999, the Isle of Dogs is now easily accessible. The DLR has also been extended to Beckton, Lewisham, London City Airport, North Woolwich and Stratford. Canary Wharf has now become one of Europe's biggest clusters of skyscrapers and a direct challenge to the financial dominance of the city of London square mile. Although most of the old Dockland wharfs and warehouses were demolished, some have been restored and converted into flats. Most of the docks themselves have survived and are now used as marinas, housing a number of high-end luxury flats within the area. The Docklands has attracted many from the traditionally exclusive West-end neighbourhoods like Chelsea, Mayfair & Knightsbridge. Canary Wharf now boasts some of London's most expensive and exclusive properties. With over 240 shops, bars and restaurants, Canary Wharf is the perfect destination for a great day out and a wonderful place to live. In the past 3 decades the population of the Docklands has more than doubled, the area has become a major business centre and an increasingly desirable area to live.
