st pancras takes you to the best places

St Pancras Station, in London, designed by George Gilbert Scott and engineered by William Henry Barlow, is seen here during the construction of the roof in October 1868.

The latticed ribs of the train shed’s roof were built by the Butterley Company, a Derbyshire ironworks firm, and erected with the aid of a giant moveable timber scaffold. The roof’s arch measures 30.5 metres by 73 metres.
