Dalton Castle, Cumbria
Dalton Castle is a grade I listed 14th-century peel tower situated in Dalton-in-Furness, Cumbria, England, and in the ownership of the National Trust.  It was constructed by the monks of Furness Abbey for the protection of the nearby market town, and was the building from which the Abbot administered the area and dispensed justice.
It was a prison from at least 1257, until 1774.
The property hosts an exhibition on a local history as well as a display about local painter George Romney.

In 1292 the Abbot of Furness claimed a right to have a gallows erected on the site. By the time of Henry VIII Dalton Castle was sadly ruined. The King ordered that its roof and floors should be repaired with lead and wood from Furness Abbey."
- Joseph Richardson (of Barrow-in-Furness, Eng.) - 1880 Furness, Past and Present: Its History and Antiquities "Dalton Castle is closely connected with the ecclesiastical history of the parish, at the present day it stands in almost the same condition in which it is represented in an illustration published seventy years ago by Close. What change has supervened is for the worse ; as it consists of the building of a plain dwelling house along the chief front of the castle, and the obscurement of what should have remained an isolated erection. West advances a Roman origin for this castle. He urges that among other facts, the nature of the situation of the fort at Dalton, are circumstances which warrant a supposition that Agricola had visited and reduced Furness in the summer of his second campaign a.d. 79 ; and that he or some successor had erected a castellum at Dalton."
