The National Trust for Scotland for Places of Historic Interest or Natural Beauty, commonly known as the National Trust for Scotland is a Scottish conservation organisation. It is the largest membership organisation in Scotland and describes itself as "the conservation charity that protects and promotes Scotland's natural and cultural heritage for present and future generations to enjoy".The Trust owns and manages around 130 properties and 180,000 acres of land, including castles, ancient small dwellings, historic sites, gardens, and remote rural areas. It is similar in function to the National Trust, which covers England, Wales, and Northern Ireland, and to other national trusts worldwide.
Alloa Tower in Alloa, Clackmannanshire in central Scotland is an early 14th century tower house that served as the medieval residence of the Erskine family, later Earls of Mar. Retaining its original timber roof and battlements, the tower is one of the earliest, and largest, of Scottish tower houses, with immensely thick walls. It was designated as a scheduled monument in 1960 and is now owned by the National Trust for Scotland.
