Conwy Castle is a medieval fortress built by King Edward I during his conquest of Wales, completed in just about four and a half years from 1283 and designed by master mason James of St George. Its eight great cylindrical towers and the town walls that encircle Conwy survive so completely that it is regarded as one of the finest works of late-13th-century military architecture in Europe, and in 1986 it was inscribed as part of the UNESCO World Heritage Site 'Castles and Town Walls of King Edward in Gwynedd.' Now a magnificent roofless ruin cared for by Cadw, the Welsh Government's historic environment service, in 2026 it still lets visitors climb its well-preserved towers and battlements for sweeping views over the estuary and the mountains of Eryri (Snowdonia).

Fine defensive detail: Britain's earliest surviving stone machicolations, a 91-foot spring-fed well and the original whitewashed limestone finish
Good to know
SafetyInteriors have narrow spiral stone staircases, uneven floors and battlement walks with low parapets and steep drops. Wear sturdy non-slip shoes and hold children's hands on the walls and towers.
SeasonNorth Wales is windy and often wet even in summer, and the roofless castle offers little shelter. Bring a waterproof and a warm layer; winter hours (Nov–Feb) are shorter, so visit in the morning.
RulesBooking online through the official Cadw site saves about 5% but is non-refundable. Last admission is 30 minutes before closing, and the site is closed on 24–26 December and 1 January.
MannersConwy station is a request stop, so tell the conductor in advance if you intend to alight there. The spiral staircases inside are narrow — give way courteously to people coming the other direction.
CautionBuy tickets only from the official Cadw website or the on-site box office; third-party resale sites that appear high in search results may add fees and charge more.
RulesIf you plan to see several castles, a Cadw multi-site Explorer Pass may be better value. Prices, opening hours and pass terms should be confirmed on the official site before you go.
Practical info
Conwy railway station is about a 5-minute walk away, but it is a request stop, so alert the conductor; alternatively use Llandudno Junction (where most trains call) and take a bus or taxi. The castle has no car park, so use the adjacent council-run Vicarage Gardens or nearby Morfa Bach pay-and-display car parks. Opening is seasonal (roughly 9:30–18:00 in summer, 10:00–16:00 in winter) with adult admission around £12.50, but confirm current prices, hours and closure dates on the official Cadw website.
