Beaumaris Castle (/bjuːˈmærɪs/ bew-MAR-is; Welsh: Castell Biwmares Welsh pronunciation: [kastɛɬ bɪuˈmaːrɛs]), in Beaumaris, Anglesey, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.

a great castle to explore with views over the se and the Llyn peninsula. It has an informative video that explains its history and then a walk across the bridge that leads you through the fortifications. you can then explore all the rooms that have exhibits of the castles history within them. to finish off you can climb the tower to see the view. Great for kids as there is a park next to it and a cafe across the bridge to keep everyone happy. Parking is available on site but it is a small carpark.

The best time to visit North Wales castles generally depends on your preferences. Spring (April-May) and Autumn (September-October) offer pleasant weather for exploring, fewer crowds, and beautiful landscapes. Summer (June-August) is popular for its warmer temperatures but can be busier. Winter visits are possible, but some facilities might have reduced hours, and weather conditions can be more challenging for outdoor activities.
While many medieval castles present accessibility challenges due to their historic nature, some sites have made efforts to improve access. For specific accessibility information, it's always best to check the official websites of individual castles before your visit. For example, Cadw (Welsh Government's historic environment service) provides detailed access information for the castles they manage, such as cadw.gov.wales.
Dog policies vary significantly between castles. Some sites may allow dogs in outdoor areas or on leads, while others may restrict access to certain parts or entirely. It is highly recommended to check the specific dog-friendly policies on the official website of each castle you plan to visit before your trip to avoid disappointment.
For major castles like Conwy Castle or Caernarfon Castle, it's advisable to allow at least 2-3 hours to explore thoroughly. This allows time to walk the battlements, climb towers, visit any museums or exhibitions within the castle, and soak in the atmosphere. If you wish to explore the surrounding town or enjoy a meal, you might consider dedicating half a day or more.
Most major castles, especially those located within or near towns like Conwy, Caernarfon, or Denbigh, will have cafes, pubs, and restaurants within easy walking distance. Smaller or more remote castles might require a short drive to the nearest village or town for refreshments. It's always a good idea to check local listings or maps for options near your chosen castle.
