Northern Wales III: Beaumaris

Beaumaris is on a big island, the Isle of Anglesey, and like Conwy it was a castle town, an English enclave surrounded by Welsh guerrillas.  Begun in 1295 in response to a revolt a year earlier, it was the last link in King Edward’s “Iron Chain” of castles enclosing Gwynedd, the former kingdom of North Wales.  Beaumaris Castle is a high point of medieval Beaumaris Castle (photo of a picture)castle design.  Built on flat marshy ground with no natural defenses, the castle incorporates concentric rings of fortifications – a double ring of walls surrounded by a moat.  The innermost wall is higher than the outer, providing greatly increased firepower.  A fortified dock was built to give sea access, allowing the castle to withstand sieges (as shown in the picture, the sea is more distant now).  However, problems in Scotland shifted the king’s priorities, and the castle was never finished.  An artist’s concept Artist concept of the completed Beaumaris Castleof what the castle would have looked like, had it been finished, is shown to the left.  The picture shows a much more imposing structure that would have been twice the height of the squat one we see today.  The inner walls look particularly impenetrable.  The south gate seen at the lower right faced the sea and was the main castle entrance as well as the dock.  A magnification of this artist’s rendition is shown below, along with a picture of the way it looks now.  The red arrows point to the dock’s

door to the castle.  Rather than using a harbor, this man-made dock used a wide shipping channel (now covered over) to deliver supplies.  Ships up to 40 tons could sail in at high tide and unload goods through the castle wall doorway.  The dock would be defended from the Gunner’s Walk, which can be seen to the right of the arrow in the left picture above, as well as at the top of the castle schematic Schematic of the Beaumaris Castleshown here.  Beneath the Gunner’s Walk was a corn mill for self-sufficiency, the mill turned by differences in water level between the moat and the sea.  Whereas the water in the dock was supplied by the sea, the water in the moat was supplied by a freshwater stream; the level between the two was regulated by a sluice gate in the Gunner’s Walk.  How clever!  The town wall started from here, but wasn’t finished until 1414.

The main entrance to the castle, shown in the paired pictures above, is to the left of the dock and was very well protected.  First there was the moat, then a drawbridge, then the outer gate.  If you got through that, there were the multiple defenses of the inner gate, with every stage having high- and low-level arrow loops.  The inner-wall gatehouse was defended by a barbican, then by three successive pairs of barred gates and portcullises.  Further, the outer wall south gate was off-set from the inner gatehouse, so attackers moving between gates would be exposed from more sides to archers waiting above.

Pictures of the outer walls, which form a rough octagon, are shown below.  The walls had 15 towers, and with arrow loops at two or three levels there were over 300 shooting

positions for the archers inside.  And of course the taller inner walls provided yet more firepower.

From the schematic of the castle shown above, you can see there isn’t a lot of space between the inner and outer walls – it’s function was to be a killing space.  As shown in the pictures below, the inner walls look forbidding, but imagine them being twice that height

had the castle been finished.   The inner walls are 16 feet thick, with inner passageways – and plenty of latrines!  The inner walls sometimes have 3 levels of latrines, examples shown below.

OK, let’s enter the inner ward!  Beaumaris would have been the largest of King Edward’s

castles, and the intended accommodation within the inner ward, shown in the first picture below, was planned on a lavish scale.  It would have had first-floor stables, kitchens, great hall and private chambers.  Both gatehouses were planned to have grand arrangements of state rooms for the king and his family, an example shown in the second picture below.

The last picture above shows the unfinished north gate dominating the courtyard.

The castle also has a chapel; it’s in one of the inner wall middle towers (called the chapel tower, of course), and is accessible either from the inner ward or from the inner wall passageway.

We’ll close with beautiful views from the castle across the Menai Straight to the

Snowdonia Mountains beyond.
