London is the starting point for a number of motorway routes. The M25 is an orbital motorway which enables vehicles to avoid travelling through central London and is one of the busiest motorways in Europe.
St Pancras is termed as the "Cathedral of the railways" and includes two of the most celebrated structures built in Britain in the Victorian era. The main trainshed (completed 1868), by the engineer William Henry Barlow, was the largest single-span structure built up to that time. In front of it is St Pancras Chambers, formerly the Midland Grand Hotel (1868-77), one of the most impressive examples of Victorian gothic architecture. Designed by architect George Gilbert Scott, the building initially appears to be in a polychromatic Italian Gothic style - inspired by John Ruskin's Stones of Venice - but on a closer viewing, it incorporates features from a variety of periods and countries. From such an eclectic approach Scott anticipated that a new genre would emerge. Access to the spectacular interiors of the former hotel is by tour only.
Sir Leslie Patrick Abercrombie (6 June 1879 – 23 March 1957) was an English town planner. After training as an architect, he became Professor of Civic Design at the Liverpool University School of Architecture, and later Professor of Town Planning at University College London. He was closely involved in the founding of the Council for the Preservation of Rural England (CPRE). After its formation in December 1926, he served as its Honorary Secretary. He was knighted in 1945. In 1948, he became the first president of the newly formed International Union of Architects or UIA (Union Internationale des Architectes).
Abercrombie is best known for the post-Second World War replanning of London and other British and international cities. He created the County of London Plan (1943) and the Greater London Plan (1944) which are commonly referred to as the Abercrombie Plan. The two plans proposed widespread reconstruction and replanning of the city and the urban areas of the surrounding counties and road and rail infrastructure including the construction of a series of concentric ring roads and underground rail loops to connect main line stations below ground to replace surface routes.
