The historic places in our care span six millennia and include palaces, houses, hill figures, castles, abbeys, industrial sites, Roman forts and even deserted medieval villages. Caring for these places and their collections for the benefit of this and future generations is a cornerstone of everything we do. The generous support of many donors enables us to do this. We have now embarked on the largest conservation programme in our history. Highly skilled conservation work will be carried out on an unprecedented scale, and we will allow the public to witness this as it progresses.
