Beyond Bramton, just over the town, is a keep ditched about, called the Mount, on the top of a hill. Hence to Thirlwal castle we rode upon the foundation of the _wall_, the river Irthing accompanying us. We visited Knaworth castle. Near here is a great house of the Howard family, built of stone, and castellated: among many family pictures, the great earl of Arundel’s, the reviver of learned curiosity among us; a library once well stored with books and manuscripts: here is the famous Glassonbury-abbey book, or rather screen, for it is big enough; an account of the saints buried in that place. In the garden are many altars and inscriptions: I copied all those tolerably fair: with much regret I saw these noble monuments quite neglected and exposed; some cut in half to make gate-posts. A fine park here, and much old timber. The country hereabouts good land and pleasant. Above the house upon a hill, a circular work double trenched; the outer ditch broadest. About Thirlwall we rode along the side of the _wall_: here was a gate through the wall, for the great Roman road called Madan-way. The name Thirlwal retains a memory of the gate here; _foramen_: we use it now to drill, and nostrill. All the fences of the inclosures, the houses, church, and Thirlwal castle, built out of the ravage of the _wall_. At the castle was a head of Roman carved work, which they have put into the blind wall of a little ale-house. VOREDA. +Caer Voran.+ A little upon the south side of the _wall_ was a great Roman city and castle. We traversed the stately ruins: it stood on a piece of high ground, about 400 foot square; had a wall and ditch; vestiges of houses and buildings all over, within and without. We observed the Madan-way coming over the fells from the south, where it passes by a work, or labyrinth, called Julian’s bower. We saw too the Roman road passing eastward along the _wall_. The country hereabouts is a wild moory bog; and the _wall_ itself climbs all along a crag, and is set upon the southern edge of it; the steepness of the cliff northward performing the part of a foss. Near Haltwistle is Baliol castle, corruptly Belister castle, said to be founded by a king of Scotland.
