Little did the Romans dream, when they fixed the eastern termination of their Wall at SEGEDUNUM, of the world-wide celebrity which its subsequent cognomen—Wallsend—would attain. Even Horsley, writing in 1731, and in what he lovingly terms 'my own county,'[54] did not foresee the extensive mining operations which shortly after his day were to take place in its immediate vicinity. In order to mark the site of the station, he fixes upon Cousin’s House, which is at some distance from the spot, whereas, the principal shaft of the celebrated mine is close beside its western rampart. SEGEDUNUM, Wallsend, is admirably selected as the site of a Roman station, and as the eastern terminus of the Wall. Without being so much[Sidenote: SEGEDUNUM.] elevated as to give it a painful exposure to the blasts of the north and of the east, it commands a view, in every direction, of the adjacent country. The ground, in front of it, slopes rapidly down to the river’s brink, and has a full exposure to the mid-day sun. The beauty of its situation is considerable now; what must it have been when aged oaks crowned the contiguous heights, and the Tyne rolled by in the brilliancy and exuberance of its youth! [Sidenote: WALLSEND.] Eastward of Wallsend, the river acquires a sufficient magnitude to make it a barrier quite formidable enough to prevent the ready passage of a foe, and to render the erection of a wall unnecessary. Frequently, however, would it be needful for the watchful eye of the Roman prefect at SEGEDUNUM to traverse the expanse which lay between him and the sea. This he could easily do. The station stands upon a bend of the river, formed by two of the longest ‘reaches’ which it makes in the whole of its course. The Long-reach extends downwards as far as the high end of South Shields, and the Bill-reach stretches nearly two miles up the water. In both directions, therefore, any operations conducted on the river would be easily discerned from the station. [Sidenote: SEGEDUNUM.] Although it was not thought requisite to extend the Wall further along the northern bank of the Tyne than Wallsend, special precautions were taken to secure the mouth of the river from hostile occupation. A camp at Tynemouth, and another at North Shields, were garrisoned by troops from the head quarters at SEGEDUNUM; these frowned over the northern shore of the estuary. A subsidiary station at Tyne Lawe, near South Shields, and another at Jarrow, guarded its southern bank, whilst one at Wardley, opposite Wallsend, would effectually support, on that side of the river, the operations of the garrison in the principal encampment. All of these will be examined afterwards. [Illustration: Altar to Jupiter-Coh. IV. Lingonum]
