The original Warthole Hall was occupied by the Dykes family in about 1540 after they acquired it following Henry VIII's Reformation of the Church. Prior to then, Warthole Hall was a monastery: the manor of Warthole belonged formerly to the Abbey of Calder.
This building was demolished in about 1670 as that's when the replacement hall was built.
The original Warthole Hall would have looked something like this.
This photograph is of Blencow Hall which is also in Cumbria. It is a fortified manor house, and the original manor house is in the middle, with the fortifications in the form of towers at each end. The replacement Warthole Hall, built in 1670 (and demolished in 1830) was built to a design by William Thackery of Thorpenhow.
At about the same time, William Thackery also remodelled Drawdykes Castle, which is situated close to Hadrian's Wall on the North-East side of Carlisle, and it is possible that Warthole Hall was a larger version of this style of house.

Cockermouth Castle is now a private home, but the owners occasionally open it up to the public, and here is a picture of the dungeon where Thomas Dykes uttered the words "rather broken than bent" when he would not renounce allegiance to the King (Charles 1st) and join the Parliamentarians, and so he was tortured and left to die in the dungeon at Cockermouth Castle. Note that the dungeon only has one small window.
