What protection from development there is for historic battlefields.

Historic Environment Scotland has a statutory duty to compile and maintain an Inventory of historic battlefields of national importance. The inclusion of a battlefield on the Inventory identifies it as an area of added protection where particular consideration must be given to impacts on the site. The effect of a proposed development on inventory battlefields is a material consideration in the planning system.
Scottish Planning Policy sets out the matters planning authorities should seek to protect in determining planning applications relating to historic battlefields, including protecting, conserving and enhancing their key landscape characteristics and special qualities. Where development is not within the planning system – e.g. forestry or Trunk Roads proposals, Historic Environment Scotland’s Policy Statement states that other public bodies should ensure that nationally important battlefields are given consideration within relevant strategies, plans and programmes.
The Town and Country Planning (Neighbouring planning authorities and Historic Environment)(Scotland) Direction 2015 sets out when Ministers have to be notified over planning proposals affecting historic battlefields, providing an added layer of scrutiny around battlefields.
