The English city of Liverpool was removed from UNESCO's list of world heritage sites on Wednesday because new buildings undermined the attractiveness of its Victorian docks, making it only the third site to be removed from the prestigious list. Liverpool was named a World Heritage Site by the United Nation's cultural organization in 2004, joining landmarks such as the Great Wall of China, the Taj Mahal, and the Leaning Tower of Pisa.After a vote in China by members of its World Heritage Committee, UNESCO said the new buildings in Liverpool were undermining the city's "authenticity and integrity." Liverpool — hometown of the Beatles — was put on the heritage list in recognition of its role as one of the world's most important ports during the 18th and 19th centuries and for its architectural beauty. Joanne Anderson, Liverpool's mayor, said the decision to remove the city from the list was "incomprehensible" coming a decade after UNESCO officials last visited. Anderson said she hopes to appeal the decision. #BreakingNews#Video | @MayorLpool Joanne Anderson responds to UNESCO's decision to delete Liverpool from its list of World Heritage sites. pic.twitter.com/PCrAsNvyu0—@lpoolcouncil "I'm hugely disappointed and concerned," she said. "Our World Heritage site has never been in better condition having benefitted from hundreds of millions of pounds of investment." The only other sites stripped previously of the title are a wildlife sanctuary in Oman in 2007 after poaching and habitat loss and the Dresden Elbe valley in Germany in 2009 when a four-lane bridge was built over the river. The heritage label gives historic sites access to UN conservation funding as well as featuring in tourist guidebooks across the world. The threat of being de-listed has hung over Liverpool since 2012 after UNESCO warned that plans for flats and offices would destroy the city's skyline. Plans for Everton football club's new stadium on part of the former docks were approved earlier this year despite objections from conservation bodies.
