With work about to start in London on the construction of the world’s largest Ferris wheel, opponents are saying it will ruin views of the British capital’s historic skyline. The $32-million Millennium Wheel will tower 433 feet above the south bank of the river Thames, which winds through central London. “This structure will seriously impinge on some of London’s finest views,” said Lord St. John, chairman of the Royal Fine Arts Commission. He said he hoped there would be no extension to the wheel’s five-year lifespan. “The sooner the wheel is taken down the better.”
