About
The last and most technically accomplished of Edward I's Iron Ring of castles, Beaumaris was begun in 1295 and — despite never being fully completed — is considered the finest example of concentric castle design in Britain. A UNESCO World Heritage Site managed by Cadw, it sits at the water's edge in the handsome Georgian town of Beaumaris with views across the Menai Straits to Snowdonia. The water-filled moat and the sheer precision of its geometry are extraordinary even after 700 years.

Frequently asked questions
Do I need to book in advance?
Online booking is recommended in summer and saves 5% on entry. Walk-up admission is available but the castle can be busy on peak summer days. Book via the Cadw website.
Is Beaumaris Castle dog friendly?
Yes — dogs on leads are welcome on the ground floor levels. Dogs are not permitted on the upper wall walks.
How long should I allow for a visit?
Most visitors spend 1–2 hours. Add extra time if you plan to combine the castle with a walk along Beaumaris pier and a stop at Red Boat Ice Cream.
Is it worth buying a Cadw membership?
If you plan to visit multiple Cadw sites on your trip (Beaumaris Castle, Bryn Celli Ddu, Penmon Priory are all nearby), a Cadw Explorer Pass may offer better value than paying per site.
