St Pancras, a railway station terminus celebrated for its Victorian architecture by William Henry Barlow, stands on Euston Road in St Pancras, London Borough of Camden, between the British Library, King's Cross station and the Regent's Canal.

The materials used are wrought-iron framework of lattice design, with glass covering the middle half and timber (inside)/slate (outside) covering the outer quarters.

The two end screens are glazed in a vertical rectangular grid pattern with decorative timber cladding around the edge and wrought iron finials around the outer edge.

It is 679 feet (207 meters) long, 236 feet (72 meters) wide, and 98 feet (30 meters) high at the apex above the tracks.

It is opened in 1868 by the Midland Railway as the southern terminus of its main line, which connects London with the East Midlands and Yorkshire.

At this time, the arched train shed is the largest single-span roof in the world.
