was excavated, and a large observation tower overlooks the site. A portion of the original wall is visible across the street from the museum, and a reconstruction of what the whole wall might have looked like. The central section of Hadrian's Wall was erected atop the Whin Sill, a geological formation that offers a natural topographic defence against invaders or immigrants from the north. However at the eastern end of the wall, the main topographic defence was the River Tyne itself, and the very final stretch of the wall ran down from Segedunum fort to the river's edge. There may have been a statue or monument to mark the very end of the wall, but if there ever was, it no longer exists. North Tyneside Council provided accommodation in the newly built Battle Hill Estate for the owners of all the houses demolished when the site was cleared. The name Wallsend comes from Segedunum being at the easternmost end of Hadrian's Wall; the westernmost end is at Bowness-on-Solway.
