This narrow stream, with its
steeply-sloping banks and winding shores, looks more like a river than a
strait, and it everywhere discloses evidence of the residence of an
almost pre-historic people in relics of nations that inhabited its banks
before the invasion of the Romans. There are hill-forts, sepulchral
mounds, pillars of stone, rude pottery, weapons of stone and bronze; and
in that early day Mona itself, as Anglesea was called, was a sacred
island. Here were fierce struggles between Roman and Briton, and Tacitus
tells of the invasion of Mona by the Romans and the desperate conflicts
that ensued as early as A.D. 60. The history of the strait is a story of
almost unending war for centuries, and renowned castles bearing the
scars of these conflicts keep watch and ward to this day. Beaumaris,
Bangor, Caernarvon, and Conway castles still remain in partial ruin to
remind us of the Welsh wars of centuries ago. On the Anglesea shore, at
the northern entrance to the strait, is the picturesque ruin of
Beaumaris Castle, built by Edward I. at a point where vessels could
conveniently land. It stands on the lowlands, and a canal connects its
ditch with the sea. It consists of a hexagonal line of outer defences
surrounding an inner square. Round towers flanked the outer walls, and
the chapel within is quite well preserved. It has not had much place in
history, and the neighboring town is now a peaceful watering-place.

Across the strait is Bangor, a rather straggling town, with a cathedral
that is not very old. We are told that its bishop once sold its peal of
bells, and, going down to the shore to see them shipped away, was
stricken blind as a punishment for the sacrilege. Of Bangor Castle, as
it originally stood, but insignificant traces remain, but Lord Penrhyn
has recently erected in the neighborhood the imposing castle of Penryhn,
a massive pile of dark limestone, in which the endeavor is made to
combine a Norman feudal castle with a modern dwelling, though with only
indifferent success, excepting in the expenditure involved. The roads
from the great suspension-bridge across the strait lead on either hand
to Bangor and Beaumaris, although the route is rather circuitous. This
bridge, crossing at the narrowest and most beautiful part of the strait,
was long regarded as the greatest triumph of bridge-engineering. It
