Description of Hadrian’s Wall

As first planned, the Wall consisted of a wall of stone or turf fronted by a wide and deep ditch. The original plan was for a guarded gate (milecastle) every mile, with two observation towers (turrets) in between. Before work was completed, 14 new forts were added, together with an earthwork known as the Vallum to the south.

WHAT SURVIVES

The surviving remains of Hadrian’s Wall consist not just of the Wall itself, but a variety of associated elements:

  • forts and civil settlements
  • milecastles and turrets
  • towers
  • bridges
  • temples
  • the ditch with an upcast mound to the north
  • the forts, milefortlets and towers of the Cumbrian coast
  • the Vallum earthwork with its causeways and crossings
  • the road known as the Military Way along the Wall and the Stanegate to the south
  • earlier and contemporary forts along the Stanegate.

All these sit within a wide contemporary Roman military landscape containing at least five forts to the north and many as far south as the legionary bases at York and Chester, and indeed beyond.
