of their ancient castles. On the site of British earthworks the Romans
established their camps. The Saxons were obliged to erect their rude
earthen strongholds in order to keep back the rebellious Welsh, and
these were succeeded by Norman keeps. Monmouthshire is famous for its
castles; out of the eleven hundred erected in Norman times twenty-five
were built in that county. There is Chepstow Castle, with its early
Norman gateway spanned by a circular arch flanked by round towers. In
the inner court there are the gardens and ruins of a grand hall, and in
the outer the ruins of a chapel with evidences of beautifully groined
vaulting, and also a winding staircase leading to the battlements. In
the dungeon of the old keep at the south-east corner of the inner court
Roger de Britolio, Earl of Hereford, was imprisoned for rebellion
against the Conqueror, and in later times Henry Martin, the regicide,
lingered as a prisoner for thirty years, employing his enforced leisure
in writing a book in order to prove that it is not right for a man to be
governed by one wife. Then there is Grosmont Castle, the fortified
residence of the Earl of Lancaster; Skenfrith Castle; White Castle, the
_Album Castrum_ of the Latin records, the Landreilo of the Welsh, with
its six towers, portcullis, and drawbridge flanked by massive tower,
barbican, and other outworks; and Raglan Castle, with its splendid
gateway, its Elizabethan banqueting-hall ornamented with rich stone
tracery, its bowling-green, garden terraces, and spacious courts, an
ideal place for knightly tournaments in ancient days. Raglan is
associated with the gallant defence of the castle by the Marquis of
Worcester in the Civil War.

The ancient castles of England were the central feature of feudal
society. They were the outward and visible sign of that system. M.
Guizot in his _History of Civilisation_ says, "It was feudalism which
constructed them; their elevation was, so to speak, the declaration of
