Arnside Tower is a late-medieval tower house (or Pele tower) between Arnside and Silverdale immediately to the south of Arnside Knott in Cumbria, England.HistoryArnside Tower was built in the second half of the 15th century; tower houses were then often built in the insecure areas of northern England and southern Scotland. Constructed of limestone rubble, the tower was originally five storeys high, measuring 50 feet by 34 feet. The tower was built with an adjacent wing of equal height built onto the side of the tower in a style common in Scotland, but rare in English tower houses. Historian Anthony Emery suggests that the design may have been influenced by that at Ashby de la Zouch Castle, rebuilt in 1464 by Lord Hastings. The tower suffered a serious fire in 1602 but after repairs remained in use until the end of the 17th century.One of the walls of the tower collapsed around 1900, and as of 2014, English Heritage considered the condition of the castle to be very bad and urgent works are required. Arnside Tower is a Scheduled Monument and Grade II* listed building.TourismThe tower is in private ownership and is in a ruinous state. The local tourist board recommends that good views of the tower can be made from the public footpath which runs alongside.
