The Royal County of Berkshire, more commonly known as simply Berkshire (/ˈbɑːrkʃɪər, -ʃər/ BARK-sheer, -shər; abbreviated Berks.), is a ceremonial county in South East England. It is bordered by Oxfordshire to the north, Buckinghamshire to the northeast, Greater London to the east, Surrey to the southeast, Hampshire to the south, and Wiltshire to the west. The county town is Reading. The county has an area of 1,262 km2 (487 sq mi) and a population of 911,403. The latter is concentrated in the east, the area closest to Greater London, and includes the county's largest towns: Reading (174,224) Slough (164,793), Bracknell (113,205), and Maidenhead (70,374). The west is rural, and its largest town is Newbury (33,841). Berkshire is governed by six unitary authorities: Bracknell Forest, Reading, Slough, West Berkshire, Windsor and Maidenhead, and Wokingham. The historic county included the parts of Oxfordshire south of the River Thames, which formed its northern border, but excludes Caversham and Slough. (Source: Wikipedia.org, CC BY-SA)
