Caerphilly Castle

The fortress sprawls over a huge area making it the largest castle in Wales.

Proudly standing on a 30-acre site, Caerphilly Castle is one of the largest fortresses in Europe. Boasting a tower which 'out leans' that of Pisa, the castle also receives visits from the infamous ghost of the Green Lady.

Stretching over a thirty-acre site in the centre of Caerphilly, this imposing Castle is a striking testament to the turbulent times of medieval Wales. Located close to the site of a former Roman fort, the building of Wales' largest castle began in 1268, under orders from the Anglo-Norman Lord Gilbert de Clare. Its construction acted as powerful symbol of Anglo-Norman rule and reinforced de Clare's control over the conquered lands of the Marchia Wallia.

Its magnificence no doubt struck fear into the hearts of the local people. Its formidable stone and water 'concentric' defences provided protection from the Welsh and in particular against the threat of Gruffydd ap Llywelyn - the Prince of Wales. Llywelyn launched his first attack against the Castle even before its defences were complete. The fortress also played an administrative role, replacing the local court of the commote as the centre of administration and revenue collection.

Throughout the late thirteenth and early fourteenth century, the Castle continued to be the focus of Welsh attacks. In 1316 Llywelyn Bren a noble of Senghenydd, raised an army of ten thousand men and attacked the Castle. The attackers failed to breach its defences, although much of the town of Caerphilly was destroyed.

By the mid-fourteenth century relative calm had fallen upon Caerphilly and parts of the Castle were probably abandoned. However, its upkeep continued throughout the fifteenth century, when the Beauchamp family spent a considerable sum of money improving its domestic accommodation. At the end of the century the Castle was leased to the Lewis family. They 'robbed' its stone to improve their own home at Van Mansion.

The Castle's role in the Civil War is far from clear. Reputedly, its massive medieval defences were damaged by gunpowder, but there is no evidence to support this. Beyond these defences an earthen redoubt was built. Whether the Royalists or Parliamentarians raised this gun platform is again unclear, as is the nature of any battle that ensued.

In the late eighteenth century the Marquees of Bute acquired Caerphilly Castle, His descendants would oversee its 'great rebuilding'. Restoration of the Castle began in the late nineteenth century, under the direction of the immensely wealthy third Marquees of Bute. This work continued throughout the last century under the fourth Marquees and later the State. The result of this extensive and painstaking work is the Castle you see today.
