Allendale, often marked on maps as Allendale Town, is a village and civil parish in south west Northumberland, England. It is located within the North Pennines Area of Outstanding Natural Beauty. At the 2001 census, the parish had a population of 2,120, decreasing to 2,021 at the 2011 Census. Allendale is within the North Pennines Area of Outstanding Natural Beauty (AONB); the second largest of the 40 AONB's in England and Wales. The local economy is predominantly based on agriculture (notably sheep farming) and tourism, although of late it has become a popular commuter town for Newcastle upon Tyne. Allendale is located around by road from the town of Hexham, and around from both Carlisle and Newcastle upon Tyne. History Allendale refers to the "dale" or valley of the River Allen. Evidence of prehistoric settlement has been found on the surrounding moorland. In the 16th century this area, close to the Scottish border, was a lawless and troubled place. Fortified farmhouses known as 'bastles' were constructed to protect residents and livestock against reiver raids. Allendale has a concentration of bastles, around 40 can still be seen, many as scenic ruins. Local mining for lead has occurred since Roman times, with the first smelting mill being constructed in the 1600s. The significant growth of Allendale Town and the surrounding villages was fuelled by that of the local lead-mining and smelting industries in the 19th century. The remains of two flues from the former smelting mill (between Allendale and Catton) run to chimneys up on the fells high above the village. The smelting mill is now home to the Allendale Brewery and the Allenmills Regeneration Project. In 1874 Allendale Co-operative Society was established. In 1869, the Hexham and Allendale Railway was opened to provide improved transport, but its opening coincided with a rapid decline in the industry due to cheap imports of lead. The last mines in the area closed in 1894 (although an attempt was made to re-open the mine at Allenheads in the 1970s). With the closure of the lead mines, the population rapidly declined and Allendale became a popular tourist destination for Edwardian Tynesiders seeking a country escape. The railway was finally closed to passengers in 1930 and to goods in 1950 (when the local terminus was bought by the stationmaster and opened as a caravan park.
