THE number of people visiting Chester Zoo dropped 6.2% following the London terrorist attacks in July, figures show.
The attraction was among the 20 worst affected by the attacks, according to a report by tourism group Alva (Association of Leading Visitor Attractions).
London's National Gallery was the most severely hit, with 15.2% fewer visitors in 2005 than 2004, and both the Tate Modern and the London Eye welcomed 12% fewer tourists.
The Tower of London (down 9.7%), the Science Museum (down 7%) and the British Museum (down 6.8%) also had fewer visitors last year.
Chester Zoo welcomed 1,089,257 people in 2005, 6.2% down on the previous year.
But the Tate Britain (up 58%) and Kew Gardens (up 25.6%) enjoyed a good 2005, while Portsmouth Historic Dockyard - home to Nelson's flagship Victory - welcomed 22.4% more visitors last year than in 2004 on the back of celebrations of the 200th anniversary of the Battle of Trafalgar.
As usual, the top attraction was Blackpool Pleasure Beach, although numbers fell 3.3% to 5.970 million.
The figures relate to attractions which are members of Alva, but do not include all Alva members as some, such as Alton Towers and Madame Tussauds, choose not to divulge annual statistics.
Alva director Robin Broke said: "The London bombings on July 7 and the failed attempts on July 21 had a considerable impact in central London. However, some sites outside central London benefited from additional displaced visitors.
