North Wales is renowned for its impressive medieval castles, many of which were constructed by King Edward I during his conquest of the region in the late 13th century. 

Many of the best castles to visit in Wales showcase exceptional examples of ancient architecture, breathtaking scenery and provide clues as to the lifestyles of our ancestors during a time which was completely alien to our own.

We thought we would use our knowledge of the area to put together a short list of the best castles in North Wales to visit for those who are holidaying with us at Tan Rallt Holiday Park. Let’s start off with one which is located close to our resort…

1. Conwy Castle

Located less than 12 miles away from Tan Rallt Holiday Park is the magnificent Conwy Castle. This is one of the medieval castles which was constructed under the instruction of King Edward I during the last 13th century as he sought to subdue any uprising from the locals following his invasion of the area. 

Alongside the castle are some equally impressive walls which surround the market town and provided fortification from his enemies. This is a UNESCO World Heritage Site who deemed the castle to be one of "the finest examples of late 13th century and early 14th century military architecture in Europe"

We would highly advise climbing the daunting staircases to the top of the castle towers if you are able so that you can admire views overlooking the wider North Wales region. It is truly a sight to behold.

2. Caernarfon Castle

Another UNESCO World Heritage Site, Caernarfon Castle was designed as a symbol of English dominance in the late 11th century and is now one of the best preserved castles in North Wales. 

Its polygon shaped towers, massive curtain walls and eagle tower are quite opposed to the architectural design utilised on the many other castles which were constructed in North Wales during the era. This makes a must visit for history buffs holidaying in the region.

In more recent times, Caernarfon Castle hosted the investiture of the future King Charles III as he became Prince of Wales in 1969. 

3. Beaumaris Castle

Beaumaris Castle is one of the most aesthetically blessed medieval constructions you are ever likely to see. It is considered to be a perfect example of concentric castle design, with a perfect symmetry of walls and defensive structures. It is also one of the few castles in North Wales to retain a fully functional moat which really adds to the wow factor.

This is a must visit for admirers of fine architecture and also anyone looking for pet friendly attractions in North Wales with dogs more than welcome to join their owners on a tour of the castle so long as they remain on a lead and do not venture off the ground floor. 

Another facet which makes Beaumaris Castle famous is that it is one of the few unfinished castles in the region. This was due to King Edward’s war with Scotland which required the monarch to divert financial resources away from his efforts in Wales during the period. 

4. Denbigh Castle

Despite being partially in ruins, Denbigh Castle is still a must visit for history fanatics and anyone who is in search of stunning countryside views.

Built by Henry de Lacy, one of King Edward I's lords, Denbigh Castle was intended to be occupied by English immigrants. Henry de Lacy reasoned that the inhabitants would be protected from the locals by the construction of the castle and its adjoining town walls. Sadly for him, the castle was temporarily seized by the Welsh prior to its completion.

In addition to providing tourists with a fascinating insight into the politics which blitzed the region throughout the medieval period, Denbigh Castle is also a fantastic location from which to admire dramatic views overlooking the Vale of Clwyd. The castle itself is also quite imposing in appearance, no doubt contributed to by its elevated position at the centre of this thriving market town.

5. Harlech Castle

Another creation of King Edward I, Harlech Castle sits majestically atop a rocky hill, overlooking Tremadog Bay. It is famous for its strategic location and the long siege it endured during the Wars of the Roses. 

A recent addition to the castle has been its ‘floating’ footbridge, which once again allows tourists to enter the building as its original architect Master James of St George had intended for the first time in over 600 years.

Under Master James’ guidance, Harlech Castle was completed in just 7 years and incorporated the revolutionary ‘wall within walls’ design which made it a formidable fortress to commandeer. This was also contributed to by its elevated position which today allows visitors to enjoy sweeping views of Snowdonia and the North Wales coast.
