Accrington ˈækrɪŋtən is a town in the Hyndburn borough of Lancashire, England. It lies about east of Blackburn, west of Burnley, east of Preston, north of Manchester and is situated on the culverted River Hyndburn. Commonly abbreviated by locals to "Accy", the town has a population of 35,456 according to the 2011 census. Accrington is a former centre of the cotton and textile machinery industries. The town is famed for manufacturing the hardest and densest building bricks in the world, "The Accrington NORI" (iron), which were used in the construction of the Empire State Building and for the foundations of Blackpool Tower; famous for Accrington Stanley F.C. and the Haworth Art Gallery which holds Europe's largest collection of Tiffany glass. The name "Accrington" likely has Anglo-Saxon origins. The earliest known recording of the name is found in the Parish of Whalley records from 850, where it is written as "Akeringastun". In subsequent records, the name appears in various forms, including "Akarinton" in 1194, "Akerunton", "Akerinton", and "Akerynton" in 1258, "Acrinton" in 1292, "Ackryngton" in 1311, and "Acryngton" in 1324. The name may derive from the Old English words "æcern", meaning "acorn", and "tun", meaning "farmstead" or "village", thus possibly meaning "acorn farmstead". However, some sources argue that this interpretation is not definitive and that alternative explanations may exist. New Accrington, the southern part of the town, was historically part of the Forest of Blackburnshire. The area's abundance of oak trees can be inferred from local place names such as Broad Oak and Oak Hill. Acorns, a product of oak trees, were once a crucial food source for swine, which may have led to the naming of a farmstead after this resource. In the Lancashire dialect, "acorn" is pronounced "akran", which might have influenced the name's development. No known Old English personal name corresponds to the first element in "Accrington". Nevertheless, the Frisian names "Akkrum" and "Akkeringa", as well as the Dutch name "Akkerghem", are believed to derive from the personal name "Akker".
