Cardiff Castle is a medieval castle and Victorian Gothic revival mansion located in the city centre of Cardiff, Wales. The original motte and bailey castle was built in the late 11th century by Norman invaders on top of a 3rd-century Roman fort. The castle was commissioned either by William the Conqueror or by Robert Fitzhamon, and formed the heart of the medieval town of Cardiff and the Marcher Lord territory of Glamorgan. In the 12th century the castle began to be rebuilt in stone, probably by Robert of Gloucester, with a shell keep and substantial defensive walls being erected. Further work was conducted by the 6th Earl of Gloucester in the second half of the 13th century. Cardiff Castle was repeatedly involved in the conflicts between the Anglo-Normans and the Welsh, being attacked several times in the 12th century, and stormed in 1404 during the revolt of Owain Glyndŵr.
Beaumaris Castle, in Beaumaris, Anglesey, Wales, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.
Harlech Castle in Harlech, Gwynedd, Wales, is a Grade I listed medieval fortification built onto a rocky knoll close to the Irish Sea. It was built by Edward I during his invasion of Wales between 1282 and 1289 at the relatively modest cost of £8,190. Over the next few centuries, the castle played an important part in several wars, withstanding the siege of Madog ap Llywelyn between 1294 and 1295, but falling to Prince Owain Glyndŵr in 1404. It then became Glyndŵr's residence and military headquarters for the remainder of the uprising until being recaptured by English forces in 1409. During the 15th century Wars of the Roses, Harlech was held by the Lancastrians for seven years, before Yorkist troops forced its surrender in 1468, a siege memorialised in the song "Men of Harlech". Following the outbreak of the English Civil War in 1642, the castle was held by forces loyal to Charles I, holding out until 1647 when it became the last fortification to surrender to the Parliamentary armies. In the 21st century the ruined castle is managed by Cadw, the Welsh Government's historic environment service, as a tourist attraction.
Conwy Castle is a fortification in Conwy, located in North Wales. It was built by Edward I, during his conquest of Wales, between 1283 and 1287. Constructed as part of a wider project to create the walled town of Conwy, the combined defences cost around £15,000, a massive sum for the period. Over the next few centuries, the castle played an important part in several wars. It withstood the siege of Madog ap Llywelyn in the winter of 1294–95, acted as a temporary haven for Richard II in 1399 and was held for several months by forces loyal to Owain Glyndŵr in 1401.
Criccieth Castle is a ruined thirteenth-century castle in Criccieth, Gwynedd, Wales. It is located on a rocky headland overlooking Tremadog Bay and consists of an inner ward almost surrounded by an outer ward. The twin-towered inner gatehouse is the most prominent remaining feature and survives to almost its full height, as does the inner curtain wall. The outer curtain wall, the inner ward buildings, and the castle's other three towers are significantly more ruinous, and in places survive only as foundations.
White Castle, also known historically as Llantilio Castle, is a ruined castle near the village of Llantilio Crossenny in Monmouthshire, Wales. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. Possibly commissioned by William fitz Osbern, the Earl of Hereford, it comprised three large earthworks with timber defences. In 1135, a major Welsh revolt took place and in response King Stephen brought together White Castle and its sister fortifications of Grosmont and Skenfrith to form a lordship known as the "Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries.
Caerphilly Castle is a medieval fortification in Caerphilly in South Wales. The castle was constructed by Gilbert de Clare in the 13th century as part of his campaign to maintain control of Glamorgan, and saw extensive fighting between Gilbert, his descendants, and the native Welsh rulers. Surrounded by extensive artificial lakes – considered by historian Allen Brown to be "the most elaborate water defences in all Britain" – it occupies around 30 acres (12 ha) and is the largest castle in Wales and the second-largest castle in the United Kingdom after Windsor Castle. It is famous for having introduced concentric castle defences to Britain and for its large gatehouses. Gilbert began work on the castle in 1268 following his occupation of the north of Glamorgan, with the majority of the construction occurring over the next three years at a considerable cost. The project was opposed by Gilbert's Welsh rival Llywelyn ap Gruffudd, leading to the site being burnt in 1270 and taken over by royal officials in 1271. Despite these interruptions, Gilbert successfully completed the castle and took control of the region. The core of Caerphilly Castle, including the castle's luxurious accommodation, was built on what became a central island, surrounding by several artificial lakes, a design Gilbert probably derived from that at Kenilworth. The dams for these lakes were further fortified, and an island to the west provided additional protection. The concentric rings of walls inspired Edward I's castles in North Wales, and proved what historian Norman Pounds has termed "a turning point in the history of the castle in Britain".
Denbigh is a market town and a community in Denbighshire, Wales. Formerly the county town of the historic county of Denbighshire until 1888, Denbigh's Welsh name translates to "Little Fortress"; a reference to its historic castle. Denbigh lies near the Clwydian Hills.
Aberystwyth Castle is a Grade I listed Edwardian fortress located in Aberystwyth, Ceredigion, Mid Wales. It was built in response to the First Welsh War in the late 13th century, replacing an earlier fortress located a mile to the south. During a national uprising by Owain Glyndŵr, the Welsh captured the castle in 1404, but it was recaptured by the English four years later. From 1637 it housed a Royal mint of Charles I, which produced silver shillings. The castle was slighted by Oliver Cromwell in 1649.
Denbigh Castle and town walls were built to control the lordship of Denbigh after the Conquest of Wales by Edward I of England in 1282. The lands were granted to Henry de Lacy, Earl of Lincoln, who began to build a new walled town, colonised by immigrants from England, protected by a substantial castle and surrounded by deer parks for hunting. The work had not been completed by 1294, when the Welsh temporarily seized the castle during the Madog ap Llywelyn revolt. The defences continued to be improved, although the castle was not completely finished by the time of Henry's death in 1311.
Flint Castle in Flint, Flintshire, was the first of a series of castles built during King Edward I's campaign to conquer Wales.
Rhuddlan Castle is a castle located in Rhuddlan, Denbighshire, Wales. It was erected by Edward I in 1277, following the First Welsh War.
Laugharne Castle is in Laugharne, Carmarthenshire, Wales. The castle, located on the estuary of the River Tâf, was originally established in 1116. It was rebuilt as a Norman stronghold. There have been many alterations since then, including becoming a Tudor fortified manor house in the sixteenth century. It changed hands twice during the English Civil War, being eventually captured by Parliamentary forces in 1644.
Abergavenny Castle is a ruined castle in the market town of Abergavenny, Monmouthshire, Wales, established by the Norman lord Hamelin de Balun c. 1087. It was the site of a massacre of Welsh noblemen in 1175, and was attacked during the early 15th-century Glyndŵr Rising. William Camden, the 16th-century antiquary, said that the castle "has been oftner stain'd with the infamy of treachery, than any other castle in Wales."
The Castles and Town Walls of King Edward in Gwynedd is a UNESCO-designated World Heritage Site located in Gwynedd, Wales. It includes the castles of Beaumaris and Harlech and the castles and town walls of Caernarfon and Conwy. UNESCO considers the sites to be the "finest examples of late 13th century and early 14th century military architecture in Europe".
Grosmont Castle is a ruined castle in the village of Grosmont, Monmouthshire, Wales. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. Possibly commissioned by William fitz Osbern, the Earl of Hereford, it was originally an earthwork design with timber defences. In 1135, a major Welsh revolt took place, and in response King Stephen brought together Grosmont Castle and its sister fortifications of Skenfrith and White Castle to form a lordship known as the "Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries.
Caernarfon Castle is a medieval fortress in Gwynedd, north-west Wales. The first fortification on the site was a motte-and-bailey castle built in the late 11th century, which King Edward I of England began to replace with the current stone structure in 1283. The castle and town established by Edward acted as the administrative centre of north Wales, and as a result the defences were built on a grand scale. There was a deliberate link with Caernarfon's Roman past—nearby is the Roman fort of Segontium—and the castle's walls are reminiscent of the Walls of Constantinople.
Conwy's town walls are a medieval defensive structure around the town of Conwy in Wales. The walls were constructed between 1283 and 1287 after the foundation of Conwy by Edward I, and were designed to form an integrated system of defence alongside Conwy Castle. The walls are 1.3 km (0.81 mi) long and include 21 towers and three gatehouses. The project was completed using large quantities of labourers brought in from England; the cost of building the castle and walls together came to around £15,000, a huge sum for the period. The walls were slightly damaged during the rebellion of Owain Glyndŵr in 1401, but political changes in the 16th century reduced the need to maintain such defences around the town. The fortifications were treated sympathetically during the development of the road and railway systems in Conwy during the 19th century and survived largely intact into the modern period. Today the walls form part of the UNESCO World Heritage Site administered by Cadw. Historians Oliver Creighton and Robert Higham describe the defences as "one of the most impressive walled circuits" in Europe.
Caernarfon's town walls are a medieval defensive structure around the town of Caernarfon in North Wales. The walls were constructed between 1283 and 1292 after the foundation of Caernarfon by Edward I, alongside the adjacent castle. The walls are 734 m (2,408 ft) long and include eight towers and two medieval gatehouses. The project was completed using large numbers of labourers brought in from England; the cost of building the walls came to around £3,500, a large sum for the period. The walls were significantly damaged during the rebellion of Madog ap Llywelyn in 1294, and had to be repaired at considerable expense. Political changes in the 16th century reduced the need to maintain such defences around the town. Today the walls form part of the UNESCO World Heritage Site administered by Cadw. Archaeologists Oliver Creighton and Robert Higham describe the defences as "a remarkably intact walled circuit".
Porth yr Aur is a Grade I listed 13th-century fortification in Caernarfon which forms part of Caernarfon Castle's medieval defences. Originally known as the West gate it was the main seaward entrance to the walled town. The building has been the home of the Royal Welsh Yacht Club since 1854. Porth yr Aur forms part of the Castles and Town Walls of King Edward in Gwynedd UNESCO world heritage site.
