Conwy Castle

Conwy Castle: A Medieval Marvel in North Wales

Edward I built Conwy Castle in just four years, between 1283 and 1287. That pace was deliberate: he wanted a defensible English stronghold in the heart of Wales as quickly as possible, and he was willing to spend what it took. The castle is part of the “Iron Ring,” a coordinated network of fortifications including Caernarfon, Harlech, and Beaumaris, designed by military architect James of St George – widely considered the finest castle builder of medieval Europe. Conwy is the most complete of the four and the most immediately impressive when you see it from the estuary.

The whole ensemble – castle, town walls, and the medieval street grid within – is a UNESCO World Heritage Site. It is one of the best-preserved medieval walled towns in Europe, and unlike many such places it is still a functioning community rather than a museum piece.

The Castle

Entry in 2026 costs £12.50 for adults in peak season, £11.90 from September to May. Online booking saves 5 percent. Children under 5 free. Cadw members enter free. A significant note for visitors planning to walk the town walls: Cadw has closed sections of the walls for safety improvements and plans to install stronger railings and protective mesh, with reopening hoped for around Easter 2027. Check the current access situation at cadw.gov.wales before planning around the wall walk.

The castle’s eight towers and the wall walks between them give some of the best views available in North Wales: the estuary, Snowdonia to the south, the town layout below. The great hall and royal apartments are roofless but the scale is apparent. The castle’s defences were never seriously tested – it was built to intimidate rather than to withstand siege, and largely succeeded.

Conwy Town

The medieval town walls, 1.3km in circuit, are among the most complete in Europe – or will be once the safety improvements are done. The Smallest House in Britain on the quay, at 3.05 metres wide and 4.72 metres tall, is either a tourist gimmick or a genuine architectural curiosity depending on how you look at it. The Conwy Suspension Bridge, designed by Thomas Telford in 1826, is a fine piece of 19th-century engineering sitting improbably close to the 13th-century castle. The juxtaposition is distinctly Welsh.

Plas Mawr, a well-preserved Elizabethan town house on the main street, is managed by Cadw and gives good insight into how the town developed beyond its medieval origins.

Eating

The Castle Hotel Restaurant on High Street does Welsh food with a modern approach – good for an evening meal, mains around £15-30. The Albion Ale House on Upper Gate Street is the better pub choice: cask ales, simple food, and the kind of room that feels like it belongs in a medieval town. For Snowdonian views with a coffee, several cafes near the quay take advantage of the estuary positioning.

Where to Stay

The Castle Hotel on High Street is the main town hotel, from around £80 per night, historic building and convenient location. Sychnant Pass House, a B&B just outside town, offers views of the surrounding countryside and more space for less money. The area around Conwy has good self-catering accommodation for longer stays.

Getting There

Conwy is on the North Wales Coast railway line, with regular direct services from Chester (around 45 minutes) and Holyhead. It is also within 30 minutes of Betws-y-Coed and the Snowdonia National Park if you have a car.
