Monument record ORF 073 - The remains of a probable World War One balloon shed, Orfordness.

The foundations of a structure centred on circa TM44254959 are visible on aerial photographs of 1942 onwards, probably marking the location of a balloon shed of World War One date on King's Marshes, Orford (S1, S2). Angus Wainwright has identified the structure as the shed where balloons that would have been used for meteorological tests and target practice would have been stored (S3). The shed also served as accommodation for a workforce, largely composed of Chinese Labour Corps, who carried out maintenance work and repaired the sea walls on the site. One of the modern banks in this area replaced this wall and is still marked on the Ordnance Survey base maps as 'Chinese Walls' (S4).
