English Heritage has warned that eight of the nation's most important battlefield sites, including the site of a major English Civil war conflict, are in danger of falling prey to developers.

The conservation organisation warned that battlefields, sites of special archaeological interest and scheduled monuments are at a much greater risk than listed buildings because local authorities often view them as a loss-making "burden". \

The Heritage at Risk (HAR) register published today lists eight of England's 43 registered battlefields as "at high risk of loss of historic significance," and a further 10 at moderate risk.
