Most destinations have some major attractions and a wide range of other attractions. For example, in London there is Buckingham Palace, Big Ben, The London Eye and Trafalgar Square, but there are hundreds of other places to visit as well. Some attractions will be free, others will be paid for. Some attractions are natural, some are purpose-built and some have become attractions over time.
Major attractions such as theme parks cost millions of pounds to build and will only be built where the company concerned is sure that the attraction will be profitable.
