Caernarfon Expands Tourism Infrastructure Linking 1283 UNESCO Castle With 25-Mile Welsh Highland Railway

The historic port town of Caernarfon in North Wales integrates 13th-century UNESCO World Heritage fortifications with 25-mile heritage railway trips into Eryri National Park.

[CAERNARFON, Wales] — Tourism and heritage disclosures from Cadw and Visit Wales highlight Caernarfon as a central culture and outdoor gateway in Gwynedd. Overlooking the Menai Strait and River Seiont on the edge of Eryri (Snowdonia), the town features Castell Caernarfon—a fortress built by Edward I beginning in 1283—alongside free-to-visit medieval town walls, independent retail corridors on Stryd y Plas, and the 25-mile Welsh Highland Railway extending to Porthmadog.

Castell Caernarfon: 1283 Fortress-Palace and UNESCO World Heritage Landmark

Dominating the waterfront, Castell Caernarfon forms part of the UNESCO World Heritage Site encompassing Edward I’s ring of castles across North Wales (including Conwy, Beaumaris, and Harlech).

Commenced in 1283, the fortress features nine stone towers and two gatehouses designed as both a royal residence and a administrative capital.

Managed by historic environment service Cadw (located at Castle Ditch, Caernarfon, LL55 2AY), the site includes ramp access through King’s Gate and a passenger lift to upper exhibition chambers.
