st could be
seen from the adjoining window recess. Of the two windows, one is
square, the other lancet-headed. The altar is modern. There is a mural
gallery in the thickness of the wall running round nearly the whole
circle of the Keep, and with remarkably strong vaulting.

Descending from the Keep and inclosing the space below, were two walls or
curtains, as they are technically called. That on the N. side, 7 feet
thick and 25 feet high, is still tolerably perfect, and within it lay the
way between the Keep and the main ward. Of the South curtain only a
fragment remains attached to the Keep.

The entrance to the court-yard--now the so-called bowling-green--was on
the N. side. On the South side, on the first floor (the basement being
probably a cellar), was the Hall, 30 feet high from its timber floor to
the wall plate. Two lofty windows remain and traces of a third, and
between them are the plain chamfered corbel whence sprung the open roof.
Below the hall is seen a small _ambry_ or cupboard in the wall.

Outside the curtain on the East side, where the visitor ascends to the
Courtyard, are remains of a kitchen and other offices with apartments
over, resting upon the scarp of the ditch.

From the N.E. angle of the curtain projects a spur work protected by two
curtains, one of which, 4 feet thick and 24 feet high, only remains, with
a shouldered postern door opening on the scarp of the ditch at its
junction with the main curtain. This spur work was the entrance to the
Castle, and contains a deep pit, now called the Dungeon, and a Barbican
or Sally-port beyond. The pit is 12 feet deep and measures 27 feet x 10
feet across. It may possibly have served the double purpose of defence
and of water supply--there being no other apparent source. In the
footbridge across the pit may have been a trap-door, or other means for
suddenly breaking communication in case of need. Overhead probably lay
the roadway for horsemen with a proper drawbridge. The thickness of the
walls indicates their having been built to a considerable height,
sufficient probably to form parapets masking the passage of the bridge.

In the mound beyond, or counterscarp, was the gate-house and Barbican,
containing a curious fan-shaped chamber up a flight of steps. While the
earth-works surrounding the Castle are the oldest part of the
fortifications--possibly, thinks Mr. Clark, of the tenth century--the
dressed masonry and the different material
