This Presentation is going to help you put together pieces of evidence to make a BIG PICTURE of the history of Caerphilly Castle. Back to Contents

Caerphilly Castle in South Wales is one of the largest castles in the United Kingdom. It was built by Gilbert De Clare between the years 1268 and By 1267 Llywelyn ap Gruffydd, the last native prince of Wales, has become lord of the greater part of Wales. He posed a threat to De Clare, the Anglo Norman lord of Glamorgan and the castle was built in response to this threat. Caerphilly is considered to be the earliest and finest example of the true regular concentric fortification in the British Isles. The water defences are thought to be modelled on those of of Kenilworth castle. There is a large collection of siege engines, based on known early examples.

1066 – The Norman Conquest of England. Harold is killed at Hastings and the Norman marcher lords are established along the Welsh border lines – Chepstow Castle is started by William fitz Osbern – The first Norman Castle is built in Cardiff – English Barons force King John into signing The Magna Carta. Limiting rights for Wales – 82 – Llywelyn ap Gruffydd (the last), prince of Gwynedd rules much of Wales.

The main gate towers are square at the base but the corners are finished in ‘spurs’. There are arrow loop windows at each of the towers three floors. Above the central gate passage, there are small holes that were used to run through ropes or chains to lift up the bridge. They were also used as murder holes, through which boiling limewater or tar was poured on the enemy if they entered the gatehouse.

The portcullis was a gate that shut over the entrances of the castle to keep out invaders and unwanted visitors. Back to ‘Defending the Castle’ Back to Contents

These were holes in the ceiling of the entrance to the castle. People in the castle would pour hot limewater or boiling tar onto invaders. Back to Contents

These were long slits in the walls where people shot arrows to kill and wound unwanted visitors.

The great hall is where most of the castles main events would have taken place. As well as having a huge fireplace to keep the building warm, the kitchens and chapel that were both important, were part of the same building and connected by doors and corridors.

Caerphilly Castle is like a floating island, surrounded by water it was very difficult to attack. Swimming across the huge moat was literally impossible and any entrances to the castle across the moat would be blocked off. Back to Contents

There are two sources of the Caerphilly Castle moat. One of the sources is the Nant y Gledyr river. The second source to the moat is the Nant y Risca River. The moat also used to be filled by natural springs, but most of them have dried up. Back to Contents

The Ballista was a giant crossbow which was first used by the ancient Greeks. On most occasions, the “bow” had twin arms each worked by tension from twisted rope or hair. The single-armed bows also worked using simple tension.

The Perrier was very similar to the trebuchet but only a bit smaller. It was used to propel stone missiles and worked by the single arm being moved by human muscle power. The Perrier being smaller, didn’t throw things as far as the trebuchet but was also used to knock down castle walls.

The Trebuchet was a heavy timber framework, with an A-frame supporting a pivot for the huge throwing arm. A strong wooden box filled with stone ballast is placed on a second pivot at the front of the arm, a rope sling for the missile is attached to the other end. The Trebuchet was very accurate and the distance it threw its missiles could be altered by the weight of the ballast.
