Number 37 in the project brings us to Arnside Tower. A Pele Tower, or more properly a Tower House. In the Middle Ages, whenever the English King’s attention was distracted, the Scots lost no opportunity of invading northern England. Castles and Pele Towers were constructed to provide protection, and in north-west England between the River Lune and the Scottish border over one hundred were built. Peles were smaller and less well fortified than castles. They were intended to counter lightly armed raiders rather than to withstand a siege by a properly equipped army. Arnside Tower was built by the De Broughton family around 1340. It was damaged by fire in 1602, but was rebuilt and survived intact until 1690. In 1815 it was sold to Daniel Wilson of Dallam and in 1884 one corner fell in a great storm. It was not rebuilt, as by this time the threat of 'liberation' from the Scots had long since diminished. Despite its heavy neglect much of it is still standing, although it is somewhat inevitably gradually disintegrating.

Pele Towers tended to conform to a pattern. They were usually three storeys high, but Arnside had four making it larger than most. The ground floor contained the dairy and store rooms. Stone steps led to a first-floor entrance, with a heavy oak door and a protective iron grille. Fire-places and latrines were built into the walls, which were up to 10 feet thick. A spiral staircase connected the floors. Arnside Tower occupies an interesting position. It is sited on a saddle between Arnside Knot to the north and Castlebarrow to the south. To the west the land slopes to the shore, and on the east to the Arnside and Silverdale Mosses. It is within visual or signaling distance of several other Peles in the area such as Hazelslack and Sizergh, which would warn each other of a pending attack in the event of a sighting of enemy infantry. Nowadays the tower shares it's immediate landscape with a farm named after it operating in it's shadow, and appears to stand on land part of Dallam Tower Estate, the local manor that stretches from Milnthorpe to the North east.
