"I believe that above all, the Trust needs to be the strategic authority for advocacy and conservation, and we need to arm ourselves with resources, knowledge and experts to ensure that. Whenever or wherever there is an important heritage issue we need to be at the forefront of best practice and to be sought out as the providers of information and as the ultimate aficionado."

Mr Simon Ambrose, CEO (2017-2023)
