Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

Before the English built the town of Conwy, Aberconwy Abbey, the site was occupied by a Cistercian monastery favoured by the Welsh princes,[3] as well as the location of one of the palaces (called llys) of the Welsh princes. From Conwy: "the oldest structure is part of the town walls, at the southern end of the east side. Here one wall and the tower of a llys [palace/court house] belonging to Llywelyn the Great and his grandson Llywelyn ap Gruffydd have been incorporated into the wall. Built on a rocky outcrop, with an apsidal tower, it is a classic, native, Welsh build and stands out from the rest of the town walls, due to the presence of four window openings. It dates from the early 13th century and is the most complete remnant of any of his Llys." The location also controlled an important crossing point over the River Conwy between the coastal and inland areas of North Wales, that Deganwy Castle for many years had defended.

Wales is rich in history, with many castles dating back to the 13th-century conquests of Edward I. Notable examples include Conwy Castle and Caernarfon Castle, both UNESCO World Heritage sites known for their strategic importance and impressive architecture. Pembroke Castle is significant as the birthplace of Henry VII, and Chepstow Castle stands out as one of the earliest Norman stone fortifications in Britain.
Many Welsh castles are set in dramatic landscapes. Dinas Bran Castle offers fantastic views of the Dee Valley and the cliffs of World's End. Harlech Castle provides breathtaking panoramic views of the Irish Sea and Snowdonia mountains. Carreg Cennen Castle is perched on a rocky outcrop, offering stunning vistas of the surrounding countryside.
Yes, several castles are great for families. Conwy Castle and Caernarfon Castle are both listed as family-friendly, allowing visitors to explore royal chambers and battlements. The Bishop's Palace and St David's Cathedral complex also offers an engaging historical experience for all ages.
The best time to visit Welsh castles is generally during the spring (April-May) and autumn (September-October) when the weather is milder and the crowds are smaller. Summer (June-August) offers longer daylight hours and warmer temperatures, ideal for exploring, but can be busier. Winter visits are possible, but some facilities might have reduced hours, and weather can be unpredictable.
Yes, many castles are situated in areas with excellent outdoor opportunities. For instance, the area around castles in North Wales is close to Snowdonia National Park, offering numerous hiking routes. You can find various hiking options, including easy, moderate, and difficult trails, by exploring the Hiking in Wales guide on komoot.
Beaumaris Castle on Anglesey is renowned for its near-perfect symmetrical concentric design, considered one of Europe's finest examples of late 13th-century military architecture. Caerphilly Castle is notable for its extensive artificial lakes and concentric defenses, making it almost impenetrable, and features a distinctive leaning tower. Raglan Castle showcases a blend of military defense and Renaissance comfort, with its hexagonal Great Tower.
Many popular castles, especially those managed by Cadw (Welsh Government's historic environment service), have on-site or nearby cafes. For example, Carreg Cennen Castle has a farm with a tea room offering home cooking. Smaller, more remote ruins like Dinas Bran Castle might require bringing your own refreshments, though nearby towns often have options.
While not a 'hidden gem' in the traditional sense, Dolbadarn Castle offers a unique glimpse into Welsh princely history. This small, well-preserved round tower castle controlled a vital route into medieval Gwynedd and held Owain Goch captive for over two decades. Its dramatic mountain setting adds to its appeal.
Accessibility by public transport varies greatly by castle. Major sites like Conwy Castle and Caernarfon Castle are often well-served by local bus routes or are within walking distance of train stations in their respective towns. For more remote castles, public transport might be limited, and a combination of bus/train and taxi or a longer walk may be required. It's advisable to check specific routes for each castle.
Visitors frequently praise the breathtaking views from castle battlements, the immersive historical experience of walking through ancient ruins, and the sheer scale and preservation of these medieval fortresses. The opportunity to explore royal chambers, climb towers, and imagine medieval life is a common highlight, often enhanced by the dramatic natural settings.
Carreg Cennen Castle is built on a limestone crag and features a natural cave beneath it, which can be explored. This combination of a formidable fortress and a natural cave adds a unique geological dimension to the visit.
North Wales is home to several of Edward I's formidable castles, often referred to as his 'Iron Ring'. These include Conwy Castle, Caernarfon Castle, Harlech Castle, and Beaumaris Castle. All are UNESCO World Heritage sites, showcasing advanced 13th-century military architecture.
