Reasons for Listing

One of only two surviving sea-plane hangars of this type in England and Wales. Base opened 1930 and two squadrons were based here initially, more in wartime when it played a major role in convoy protection. The base closed in 1959, the last flying boats being withdrawn February 1957.

Old photographs suggest that this was originally built as two bays with half bays each end, and enlarged to match No. 1 hangar before 1938.
