This is fascinating, as is the Historic England report on the subject. The title of the video is a teensy bit misleading, for as the report says:
It is estimated that 417 public houses (363 in England and 54 in Scotland) were acquired
or constructed by the Central Control Board and State Management Scheme between 1916
and 1973.241 This includes the public houses that were closed and remodelled under the
scheme. A total of 333 (80%) of these (290 in England and 43 in Scotland) remain standing,
but with the general decline in public house culture across the country, the future of these
buildings is uncertain.
