 The southern curtain wall is a modern replacement along the line of the medieval wall . There are the remains of two round or semi @-@ circular towers projecting from the wall . Enough of one tower survives that one can see the use of Roman tiles in the construction , probably from the fort of Navio 2 mi ( 3 km ) away . It is uncertain when these towers were built , although it is thought they may date from the 13th century . Foundations mark the position of buildings abutting the south wall , probably the old hall and a chapel . A document from 1246 recorded a chapel at the castle ; the remains of the easternmost building against the south wall are assumed to mark the site of the chapel , as they are oriented roughly east – west . Foundations at the west end of the north wall mark a large building : probably a hall where the lord of the castle would have eaten and entertained high @-@ status guests . It is unclear when the new hall was built , probably replacing the old hall in the south of the castle , although an " old hall " was mentioned in a document of 1251 , implying there was also a new hall by that time . The kitchen and food stores would have stood at the east end of the hall , although little remains of those structures . Buildings were also constructed against the west curtain wall , probably high @-@ status apartments . Although the main approach to Peveril Castle was from the north , there was also a gate in the west . A bridge spanned the gorge , linking the castle with an enclosure on the other side . As it has not been excavated , the exact form the enclosure took is uncertain . Its purpose is also a matter of speculation , whether it was an elaborate outer bailey for defence or used for storage and stabling .
