A project that is proceeding is the creation of The Queen's Diamond Jubilee Galleries in the medieval triforium of the abbey. The aim is to create a new display area for the abbey's treasures in the galleries high up around the abbey's nave. To this end a new Gothic access tower with lift has been designed by the abbey architect and Surveyor of the Fabric, Ptolemy Dean. It is planned that the new galleries will open in 2018.
