Birmingham is a city and metropolitan borough in the West Midlands county of England. Birmingham is the largest of England's core cities, and is often considered to be the second city of the United Kingdom. The City of Birmingham has a population of 1,006,500 (2006 estimate). It forms part of the larger West Midlands conurbation, which has a population of 2,284,093 (2001 census) and includes several neighbouring towns and cities, such as Solihull, Wolverhampton and the towns of the Black Country. The city's reputation was forged as a powerhouse of the Industrial Revolution in Britain, a fact which led to Birmingham being known as "the workshop of the world" or the "city of a thousand trades". Although Birmingham's industrial importance has declined, it has developed into a national commercial centre, being named as the third best place in the United Kingdom to locate a business, and the 21st best in Europe by Cushman & Wakefield in 2007. It is also the fourth most visited city by foreign visitors in the UK. In 1998, Birmingham hosted the G8 summit at the International Convention Centre and remains a popular location for conventions. People from Birmingham are known as 'Brummies', a term derived from the city's nickname of Brum. This comes in turn from the city's dialect name, Brummagem, which is derived from one of the city's earlier names, 'Bromwicham'. There is a distinctive Brummie dialect (distinct vocabulary and syntax) and accent, both of which differ from the adjacent Black Country. The Birmingham Museum & Art Gallery is the main art gallery and museum in Birmingham. It has renowned displays of artwork that include a leading collection of work by the Pre-Raphaelite Brotherhood and the world's largest collection of works by Edward Burne-Jones. The group also owns other museums in the city such as Aston Hall, Blakesley Hall, the Museum of the Jewellery Quarter and Sarehole Mill, a popular attraction for fans of J. R. R. Tolkien. Thinktank in the Eastside is one of the newest museums in the city. The Birmingham Back to Backs are the last surviving court of back-to-back houses in the city. The Barber Institute of Fine Arts is both an art gallery and concert hall. It also has one of the world's most detailed and largest coin collections. Cadbury World is a museum showing visitors the stages and steps of chocolate production and the history of chocolate and the company. There are over 8,000 acres (3,200 ha) of parkland open spaces in Birmingham. The largest of the parks is Sutton Park covering 2,400 acres (970 ha) making it the largest urban nature reserve in Europe. Birmingham Botanical Gardens are a Victorian creation, with a conservatory and bandstand, close to the city centre. The Winterbourne Botanic Garden, maintained by the University of Birmingham, is also located close to the city centre. Woodgate Valley Country Park is in Bartley Green and Quinton. The city centre consists of numerous public squares including Centenary Square, Chamberlain Square and Victoria Square. The historic Old Square is located on Corporation Street. Rotunda Square and St Martin's Square are two of the newest squares in Birmingham, being located within the Bullring Shopping Centre. Brindleyplace also consists of three squares. Due to Birmingham's diverse population, there is a diverse variety of religious buildings in the city. St Philip's was upgraded from church to cathedral status in 1905. Another cathedral in the city is St Chad's, which is the seat of the Roman Catholic Province of Birmingham. St Martin in the Bull Ring is a Grade II* listed church. There is also a variety of non-Christian religions in the city. In the 1960s, Birmingham Central Mosque, one of the largest mosques in Europe, was constructed for the Muslim community of the city. However, during the late 1990s a mosque in the Sparkhill area close to the city centre was re-developed in partnership with the Birmingham City Council to supersede the Birmingham Central Mosque as the largest Mosque in the city. It holds a larger capacity and a fully functional segregated women's section. As its centerpiece is a dome. The new mosque is generally home to the Kashmiri-Pakistani population which made Birmingham its home during the late 1960s. More on Birmingham
