The first record we have of ownership of Patterdale Hall dates back to 1624, when the Lordship of Patterdale was purchased from the Threlkeld Family by Joan Mounsey of Greystoke for her son John, a miner. The Threlkelds were said to have had a house present on the site for many hundreds of years before this, but of this we know nothing.
During the Civil War, John Mounsey led a group of Dalesmen (men from the Dale) to Stybarrow crag to repulse the Scots, who were on their way to fight for Charles 1st at Preston. It appears that after this exploit the great John Mounsey became known as the “King of Patterdale”.
John Mounsey and his wife Dorothy rebuilt their old house in 1677 during a period of greater prosperity. Many houses in the Lake District were rebuilt at this time. A sketch plan by an antiquarian called Machell, drawn about 1680, shows the house with a cross-passage, a communal hall, kitchen, buttery and parlour i.e. a bedroom for the master and the mistress. There were also stables, a walled courtyard, terrace and orchard. The house was probably furnished with finely carved wooden furniture, a feature of the Lake District homes at that time. Certainly a throne for the king was made, bearing his initials, coat of arms and the date 1677. This chair is now in the Tullie House Museum, Carlisle.
