Bunker
Bunker is usually a term used to describe a protective, reinforced or fortified building, often underground but also free standing. Such storm, military, wartime, nuclear bunkers or safe houses were often made of thick, strong, reinforced bomb blast resilient concrete, but the term could also be used to describe dug out areas of land or trenches to protect from enemy attack. The term sangar may also be used to describe such a pit or specifically rifle pit for a soldier, often built up at the edges with loose stones.
According to Subterranea Britannica there are some 275 bunkers located in the UK, many are disused, some remain useable and some have been adapted for reuse or incorporated into developments. There are also any bunkers located across Europe, with a similar story, some being converted into art galleries, others into hotels as well as homes.
Bunker can also refer to a buildings or spaces used for storage, in particular fuel. Again built with protective walls to prevent explosion or ignition of the fuel or ammunition. The fuel used in shipping may still be referred to as bunker fuel, which dates back to when the fuel used was coal and it was stored in a bunker on board the ship.
Bunker might also be used to describe an external storage area, often partly underground, which remains a constant lower temperature and is used to store food, also referred to as an earth cellar (or root cellar in the US) with a similar function to a larder, buttery or pantry.
