English: Horsley Tower Horsley Tower (also known as Pele Tower), was built probably as late as the reign of Henry VII for the Horsleys of knightly rank. The existing building is a fine specimen of a strongly fortified tower of the fifteenth century, with a slight addition of a later period. It has a fine view to the coast and North West. A beacon, lighted on the summit of the tower at night, would be clearly seen far out at sea and would be plainly visible from the hilltops above Rothbury. Built in times of battle, as a defence against raiding Scots from across the border. It is possible that there was a building on the same site which fell into disrepair and was rebuilt as the present Tower of Longhorsley, which was destined to become, in later days, the peaceful home of the catholic clergy of the Village.
