The 1857 event was a success, but the last of its kind. As England urbanised rural sports were no longer in fashion. Instead football, horse-racing, music halls and sea-side resorts attracted the crowds. Academics also won the dating argument. King Alfred remained enormously popular in Imperial Britain, but a pagan prehistoric Horse became increasingly less attractive to the patriotic population.
Scheduled Ancient Monuments
After years of effort and opposition proponents of ancient monument protection (Sir John Lubbock and George Shaw-Lefevre) finally succeeded. The Ancient Monuments Protection Act became law in 1882. Attached to the Act was a Schedule of 68 sites in England, 21 in Scotland, 18 in Ireland and 3 in Wales. These included Wayland’s Smithy and Uffington castle. But not the White Horse – probably because of the dating dispute.
The White Horse itself was finally protected on 13 December 1929, probably because, three years before, the celebrated archaeologist Sir Flinders Petrie had surveyed the Horse and declared it to be Bronze Age in date (not very convincingly).
In this period the Horse had been neglected, though in 1892 Lady Craven paid £10 for a dozen men to clean it. It was unclear who if anyone had the responsibility to maintain it. The Daily Mail in 1922 bemoaned its neglect. Travellers on the train across the Vale complained: "something needs to be done about it".
The authorities evidently listened because in the first aerial photographs taken in the 1930s we see the White Horse in good shape. Then in 1940 it was covered over to hide the landmark from the Luftwaffe.
Today White Horse Hill is legally protected for its ancient monuments, as a Site of Special Scientific Interest and as an Area of Outstanding Natural Beauty. It is the responsibility of English Heritage and Nature England, while the land is managed by the owners, the National Trust.
