The world's largest, buried alive

St Pancras International, a railway terminus on Euston Road in the London Borough of Camden, is home to the tallest building in London up to the arrival of modern skyscrapers - the cathedral-like train shed that houses the Midland Grand Hotel, initially designed by William Henry Barlow to echo St Pancras railway station. Although St Pancras International is not a modern skyscraper, it served as a train station for nearly a century before being replaced by newer terminals. In the late 1960s, it was under threat of demolition as service was set to be diverted to King’s Cross and Ebbsfleet Stations. However, a fervent campaign led by various entities succeeded in preserving the building, ultimately resulting in it being listed as a Grade I building in 1970, just 10 days before demolition was scheduled.
