Air raid shelter
structure which protects against enemy attacks from the air
Air raid shelters are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack (but many have been used as defensive structures in such situations).
History
Pre-WWII
Prior to World War II, in 1924, an Air Raid Precautions Committee was set up in the United Kingdom. For years, little progress was made with shelters because of the apparently irreconcilable conflict between the need to send the public underground for shelter and the need to keep them above ground for protection against gas attacks. In 1935, every city in the country was given a document to prepare air raid shelters. In February 1936 the Home Secretary appointed a technical Committee on Structural Precautions against Air Attack.
By November 1937, there had only been slow progress, because of a serious lack of data on which to base any design recommendations and the Committee proposed that the Home Office should have its own department for research into structural precautions, rather than relying on research work done by the Bombing Test Committee to support the development of bomb design and strategy. This proposal was eventually implemented in January 1939.
During the Munich crisis, local authorities dug trenches to provide shelter. After the crisis, the British Government decided to make these a permanent feature, with a standard design of precast concrete trench lining.
The public source identifies “Air raid shelter” as structure which protects against enemy attacks from the air. This brief keeps that definition visible, then builds a research path around raid, shelter and structure.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Air raid shelter”, the useful work is to connect “structure which protects against enemy attacks from the air” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q389959. The Library of Congress control number is sh85002692. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1924, 1935, 1936 and 1937.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
