barracks

thumb|300px|Late 18th century barracks from the reign of George III, [[Edinburgh Castle, Scotland]] Barracks are buildings used to accommodate military personnel and quasi-military personnel such as police. The English word originates from the 17th century via French and Italian from an old Spanish word 'soldier's tent', but today barracks are usually permanent buildings. The word may apply to separate housing blocks or to complete complexes, and the plural form often refers to a single structure and may be singular in construction.

The main objective of barracks is to separate soldiers from the civilian population and reinforce discipline, training, and esprit de corps. They have been called "discipline factories for soldiers". Like industrial factories, some are considered to be shoddy or dull buildings, although others are known for their magnificent architecture such as Collins Barracks in Dublin and others in Paris, Berlin, Madrid, Vienna, or London. From the rough barracks of 19th-century conscript armies, filled with hazing and illness and barely differentiated from the livestock pens that housed the draft animals, to the clean and Internet-connected barracks of modern all-volunteer militaries, the word can have a variety of connotations.
