On the hilltop to the north of the Priory buildings (on Purdown) is the Purdown BT Tower. It is one of twelve reinforced concrete towers owned by BT in the UK. It is used mainly for point-to-point microwave links and forms part of the British Telecom microwave network. Although not open to the public, public footpaths lead, via a bridge over the M32 motorway to the lands around the tower.
