Although Birmingham in England has existed as a settlement for over a thousand years, today's city is overwhelmingly a product of the 18th, 19th, and 20th centuries, with little surviving from its early history. As it has expanded, it has acquired a variety of architectural styles. Buildings of most modern architectural styles in the United Kingdom are located in Birmingham. In recent years, Birmingham was one of the first cities to exhibit the blobitecture style with the construction of the Selfridges store at the Bullring Shopping Centre. Birmingham is a young city, having grown rapidly as a result of the Industrial Revolution starting in the 18th century. There are very few buildings remaining in Birmingham prior to this. Further loss has been demonstrated through the effects of war and redevelopment, especially following World War II. Industrialisation and planning policies have also led to Victorian buildings being demolished but the prosperity brought with it led to some of the city's grandest buildings being constructed, although in turn many of these are being or have been demolished. Industrialisation and the growth of the city led to its boundaries expanding and the city acquired other forms of architecture. As of April 2006, there are 1,946 listed buildings in Birmingham, thirteen scheduled ancient monuments and 27 conservation areas. Many well-known architects come from Birmingham. From the Victorian era, Yeoville Thomason, J. A. Chatwin and Martin & Chamberlain made a big impact on the city. In the early 20th century, Harry Weedon designed over 300 Odeon cinemas across the country. Hurley Robinson also designed numerous cinemas around the United Kingdom. William Alexander Harvey played a key part in the design and construction of Bournville. In the postwar period, John Madin became a prolific architect and more recently, Glenn Howells and Ken Shuttleworth have made their mark on the international stage. Medieval architecture Although place-name evidence indicates that Birmingham was established by the early 7th century, the exact location of the Anglo-Saxon settlement is uncertain and no known trace of it survives. The modern settlement of Birmingham was established by Peter de Birmingham in 1166 as a planned town around the triangular marketplace that would become the Bull Ring. Traces of this 12th century settlement survive in the foundations of the Birmingham Manor House, now buried under the Birmingham Wholesale Markets, and in Norman fabric from the original church of St Martin in the Bull Ring,
