Birdoswald has a good visitors' centre but is a little
disapointing when compared with Vindolanda or Chesters.
The outline of the walls of the fort are visible and
sections of each gatehouse. The granaries have been well
excavated, but the rest of the form remains protected
under a field of grass and sheep.
There are also the remains of the buildings built here
after the Roman withdrawal. First, in the 5th century,
a large timber hall - now marked out by posts, then a
medieval fortified tower. This was replaced by an
Elizabethan 'bastle house' (a defence against the
notorious 'Border Reivers'). Finally the present Victorian
farmhouse was built; its outbuildings contain the
visitors centre.
