The UK is a signatory to the EU Valletta Treaty which obliges it to have a legal system to protect archaeological heritage on land and under water. The body of designation legislation used for legally protecting heritage assets from damage and destruction is complex, and dates back to 1882. There have been many revisions since, and the UK government states that it remains committed to heritage protection legislation reform, even though the draft Heritage Protection Bill 2008, which proposed a single 'register' that included scheduled monuments and listed buildings, was abandoned to make room in the parliamentary legislative programme for measures to deal with the credit crunch.
