This evening, I am focusing on Poltross Burn Milecastle near Gilsland on Hadrian’s Wall.

Location is approximately forty-two miles west of Newcastle-upon-Tyne in N.E. England.

Poltross is a reasonably well-preserved milecastle of a type  encountered on Hadrian’s Wall.

Key aspects of milecastles:

  • Regularly spaced at one Roman mile intervals along the Wall.
  • Performed function as fortified gateway with double gates at front and rear.
  • Typically measure 60 by 50 Roman feet.
  • Contained one or two small outbuildings, possible barrack-blocks.
  • Usually contained an oven in N.W. corner and a staircase in opposite north corner to provide access via ladder to a tower over the north gate.
  • Between each milecastle (or fortlet) was situated two  observation towers (or turrets). The towers were thus spaced one-third of a Roman mile apart.
  • Garrisoned by a complement of 20-30 auxiliary soldiers.
