Almost everyone would agree that St Pancras International is London's most impressive rail terminus. The great arched train shed, designed by William Henry Barlow, was the largest single-span structure in the world at the time of its construction in 1868. This is matched up with George Gilbert Scott's fairytale castle originally known as the Midland Grand Hotel, and now reborn as residential apartments and the five-star St Pancras Renaissance London Hotel.
We got to see the parts of the station that passengers and shoppers never get to, taking a tour of the roof, back rooms and clock tower. Along the way, we met Sam Lane, one of the few people lucky enough to live in the apartments overlooking the concourse. After watching the video, the photos below give further insights into this magnificent building.
