Edgbaston (/ˈɛdʒbəstən/) is an affluent suburban area of central Birmingham, England, historically in Warwickshire, and curved around the southwest of the city centre. In the 19th century, the area was under the control of the Gough-Calthorpe family and the Gillott family who refused to allow factories or warehouses to be built in Edgbaston, thus making it attractive for the wealthier residents of the city. It then came to be known as "where the trees begin". One of these private houses is grade one listed and open to the public. The majority of Edgbaston that falls under the B15 postcode finds itself being part of the Calthorpe Estate. The estate is an active conservation area, and it is here that the areas most prized properties are situated. The exclusivity of Edgbaston is down to its array of multi-million listed Georgian and Victorian villas, making it one of the most expensive postcodes outside of London. Edgbaston boasts facilities such as Edgbaston Cricket Ground, a Test match venue, the University of Birmingham, established as Birmingham Medical School in 1825, the Birmingham Botanical Gardens, as well as eight out of the nine independent schools within the city, Elmhurst Ballet School, Edgbaston Golf Club, which is one of the private members clubs in the country, as well as the Priory Club, which offers sporting facilities. The area also has the Birmingham Botanical Gardens as well as the Edgbaston Archery and Lawn Tennis Society, which is the oldest lawn tennis club in the world that is still in use today. The first game of lawn tennis was incidentally also played in Edgbaston, in a garden of a house known as "Fairlight". The area is also home to a Michelin star restaurant, Simpsons, as well as pubs such as The Highfield, The Physician and the boutique hotel, The Edgbaston. The parliamentary constituency of Edgbaston includes the smaller Edgbaston ward and the wards of North Edgbaston, Bartley Green, Harborne and Quinton. Edgbaston is also a local government district, managed by its own district committee.
