been married to his daughter and heiress Alice. After Lancaster's execution in 1322, control reverted to the crown. The next year a new deer-leap was added at a cost of 18 shillings to allow animals to enter the park, but prevent them from leaving. In 1327 the honour was among the lands granted to Queen Isabella, the mother of Edward III. During her control of the park there are a number of records of trespass, including in 1334 when a large group including the rector of Bury broke in and carried away the venison. As the attainder of Thomas of Lancaster had been annulled, upon the death of Alice de Lacy in 1348, the honour was reincorporated into the Earldom of Lancaster, later becoming part of the Duchy of Lancaster. Before 1361 grazing rights within the park were leased out, initially to the park-keeper, and the practice continued through the 15th century. A decree issued in 1480 ordered the payments stopped to officers of the park as there was no game to keep, however is doesn't seem to have been enforced. And the rights and privileges of several officers including the park-keeper, the constable and porter of Clitheroe Castle, and the bailiff of Salford Hundred were confirmed in a 1485 act. The commissioners of Henry VII, who surveyed the crown lands in Lancashire in 1507, reported that the "closure is downe" and although the deer still had recourse within the park it was used as a pasture. Authorised to grant forest land as copyhold leases, they divided the park into eight 60 acre parcels and it was subsequently developed as farmland. The closest farms to the Tor were also granted rights to take turf and stone from the hill. The precise area of the park is somewhat uncertain as although stretches of the ditches from the enclosure still remain in the Alden and Musbury valleys, along Ogden Brook the boundary is only suggested to have been a little west of Holcombe Road. Conversion from the customary acre of the middle ages to imperial units is complicated because of the range of rod-lengths in use in Lancashire, however the area still known as Musbury Park in the 19th century was recorded to be . In the latter half of the century most of Musbury had become part of the mill-owning Porritt Estate. In the 1880s William John Porritt began to farm
