The same style of castle-building continued for a century and a half
after the Norman Conquest. It is possible to distinguish the later keeps
by the improved and fine-jointed ashlar stonework, by the more frequent
use of the stone of the district, instead of that brought from Caen, by
the ribs upon the groins of the vaulting of the galleries and chambers
in the walls, and by the more extensive use of ornaments in the bosses,
windows, doors, and fireplaces. The style of the decoration approaches
the Early English character.

The walls of the keep were not the only protection of the fortress. A
moat surrounds the whole castle, crossed by a drawbridge, protected
on the side remote from the castle by a barbican. High walls with an
embattled parapet surround the lower court, or ballium, which we enter
by a gate defended by strong towers. A portcullis has to be raised, and
a heavy door thrown back, before we can enter; while above in the stone
roof of the archway there are holes through which melted lead and pitch
can be poured upon our heads, if we attempt to enter the castle as
assailants. In the lower court are the stables, and the mound where the
lord dispenses justice, and where criminals and traitors are executed.
Another strong gateway flanked by towers protects the inner court, on
the edge of which stands the keep which frowns down upon us as we enter.

An immense household was supported in every castle. Not only were there
men-at-arms, but also cooks and bakers, brewers and tailors, carpenters,
smiths, masons, and all kinds of craftsmen; and all the crowd of workers
had to be provided with accommodation by the lord of the castle. Hence
a building, in the form of a large hall, was erected sometimes of stone,
usually of wood, in the lower or upper court for these soldiers and
artisans, where they slept and had their meals.

A new type of castle was introduced during the reigns of the three
Edwards. The stern, massive, and high-towering keep was abandoned, and
the fortifications arranged in a concentric fashion. A fine hall with
kitchens occupied the centre of the fortress; a large number of chambers
was added, and the inner and outer courts both defended by walls, as we
have already described, were introduced. The Edwardian castles of
Caernarvon and Beaumaris belong to this type of for
