Caernarfon Castle, Snowdonia, North Wales

Caernarfon castle is a mightily impressive medieval fortress, built in North West Wales during the 13th century. It is loved by all visitors for its intimidating appearance. It truly is a sight to behold! If an unforgettable experience is what you’re after, then this historical attraction will take you on a superb journey back in time. A family day out you won’t forget.

Proudly sitting in the centre of Caernarfon overlooking the straits, Caernarfon castle’s positioning only adds to its daunting presence. Sheltering the town and looking over to Anglesey, this castle is in a stunning location surrounded by sea views. If you aren't impressed by history, then you will surely be won over by the architecture and vistas to be seen here. Eight polygonal towers, colour-banded masonry, high wall walks, and a twin-towered gatehouse are all demanding to be admired. It is clear to see why this is considered one of the best attractions in North Wales and has been a part of the World Heritage Site since 1986.


In 1282 King Edward I defeated the last Prince of Wales, Llywelyn Ap Gruffudd, and was determined to conquer Wales and subdue its people. He, therefore, began building his own ‘Iron Ring’ of castles, as they are often known, including Beaumaris, Dolwyddelan, Harlech and of course Caernarfon Castle; the most ambitious and accomplished of them all! 

The build was inspired by his fascination with Roman legends surrounding Caernarfon and the Roman City of Constantinople. Much thought went into the location and design of the castle as it then acted as the administrative centre of North Wales. Caernarfon castle was deliberately placed here for the ease of access to the sea from the banks of the River Seiont, as well as the close proximity to the Roman Fort (Segontium)

While the castle was being built, King Edward I erected the town walls around Caernarfon with the intention of turning it into an English power base and these can still be seen throughout the town today. Designed to be a symbol of strength and power, these castle walls conceal an outstanding historical past which has greatly influenced the culture of North Wales into the modern day. Wandering around all of the rooms, passageways and towers, exploring all of the little nooks and crannies, the whole family will have fun learning about the exciting stories hidden within the walls! 

The well established towers showcase permanent exhibitions for the public to investigate during their visit (included in the entry fee) to truly appreciate the wonders of Caernarfon Castle. The Royal Welch Fusiliers Museum is located in two towers of the castle, telling the story of over 300 years of service by Wales’ oldest infantry regiment. The Queen’s Tower has an exhibition of uniform, guns, medals and memorabilia while the Chamberlain Tower displays the throne and paraphernalia from the ordination of Prince Charles of Wales, and the Eagle Tower contains an interactive history of the castle.  

A guided tour is also on offer while at the castle. If you don’t know where to start, I would recommend paying the additional £3 for the hour long guided tour with knowledgeable staff who can point out interesting details of the construction and reconstruction of the castle, as well as providing you with historical facts to help you make the best of your day! 

The Castle has been well preserved under the care of CADW (The Welsh Government’s historic environment service, safeguarding Wales’ heritage) - making this a safe family friendly attraction that is just as spectacular today as the day it was built. With high towers, grass courtyards and arrow slits; it is a real blast into the past! The perfect place for an adventure the whole family will enjoy!
