St. Pancras station attached to the base of one of the substantial supporting columns. The Butterley Company was a highly successful business based in Ripley, Derbyshire that was formed in 1790. It was involved in the manufacture of heavy engineering and large structures much of which revolved around the railways. One of their most famous structures was St. Pancras with them manufacturing the huge two hundred and forty foot wrought iron spans of the Barlow train shed. After surviving into recent years manufacturing things such as the Falkirk Wheel and Portsmouth's Spinnaker Tower the company was wound up in 2009 with various parts of it sold off so ending a fine heritage of heavy manufacturing and one that has gone the way of so many others.
