Our Cardiff Castle Highlights
As two passionate history fans, exploring the castles of the UK has always been something we have been keen to do.
That being said, that had all pretty much happened in England to date. Wales had always been high on the list, especially given its fascinating Celtic history, but we had never really had the chance to go there - until now.
So, of course, what better way to kick off a road trip around Wales than with a visit to its perhaps most famous pride and joy, the incredible Cardiff Castle!
A life-long ambition fulfilled, we came here with a huge sense of anticipation and we were not disappointed in the slightest.
This is a magnificent castle and one that we will not forget in a hurry!
The first of 4 Roman forts was established in Cardiff, it was strategically built alongside the River Taff, which supplied its moat and provided easy access to the sea.
Around 270 AD, the basis of the Castle’s layout today was built in stone, modified over the years as it defended the city from invasion.
It now stands as one of the most important structures in Wales and is a fascinating beacon of Roman, Welsh, and English history in the area.
With a large itinerary for the day, we got to the castle early and had very limited time.
We were only able to explore the inner castle and exterior area (Bute Park) and were desperately disappointed not to be able to go inside.
We will save that for another time! If you choose to, you can get a ticket to explore the walls of the castle, the Norman keep, its museum and perhaps its most impressive feature, the Victorian Apartments.
It was a cloudy and windy day as you can probably tell from the photos, but we still really enjoyed our time wandering through the free parts of the grounds.
The Welsh Dragon, the main castle entrance gate, and the keep on the mound are excellent features to check out.
The paid area is well sectioned off, but you can still get close enough for some good shots. Once you get past the mound of the keep, you will exit to Bute Park.
⪢ The Surrounding Gardens (Bute Park)
Bute Park is a large park (around 130 acres) located right next to Cardiff Castle. It used to be the private pleasure garden of the castle, but now it's a public park and considered the "green heart" of Cardiff.
It's a Grade 1 listed historic park with a wealth of archaeological and nature conservation interest, including a magnificent arboretum containing over 3000 rare and beautiful trees, some of which are "champion trees" - the biggest of their species in the UK.
There are remains of a medieval Blackfriars Friary within the park, and it also has a visitor center, cafes, toilets, a woodland play trail, and fitness equipment.
There is plenty to enjoy here, and when you exit the east side of Cardiff Castle, you will find yourself in the park itself.
We crossed over the River Taff and were thoroughly impressed by the arboretum which kind of reminded us of the mangroves in Langkawi (Malaysia). They are spectacular!
We also checked out the Gorsedd Stone Circle, which may look old, but was only installed in 1978. It was moved to Bute Park from Gorsedd (hence its name) to celebrate Cardiff hosting the Welsh National Eisteddfod.
This 8-day festival is considered to be the largest music and poetry festival in Europe! We did not know this at the time, but as two poets who met each other through our poetry, it was super cool to find this out afterward.
Especially as Jenn was particularly drawn to stand right in the middle of it on the large central stone overlooking the castle walls!
You can find more information on the official Bute Park website. Read on for more on the history of the castle and some impressive facts!

The History of Cardiff Castle
⪢ One of the UK's Oldest Surviving Castles
Cardiff Castle, standing tall in the heart of Wales's capital city, has a rich and storied history dating back over 2,000 years.
Its origins are traced to the Roman occupation of Britain, where a fort was constructed on the site around 55 AD.
Over the centuries, the castle evolved, with significant developments occurring during the Norman period when William the Conqueror's nephew, Robert Fitzhamon, built the first stone keep in the late 11th century.
⪢ Medieval Conflicts
Cardiff Castle has indeed witnessed its fair share of attacks and conquests throughout its history.
It was repeatedly involved in clashes between the Anglo-Normans and the Welsh during the 12th century.
A significant event occurred in 1404 when Owain Glyndŵr, a Welsh leader, successfully stormed and captured the castle during his rebellion.
⪢ English Civil War
During the English Civil War (1642-1651), the castle changed hands twice.
Royalist forces under the Marquess of Hertford captured the castle in a surprise attack, then Parliamentary forces and local troops quickly besieged and recaptured the castle within hours.
While these are the most prominent instances, it's likely the castle faced other attacks or attempts at conquest throughout its long history, particularly during periods of regional conflict.
⪢ Noble Ownership & Victorian Transformation
Subsequent generations of noble families, including the de Clare and Herbert families, expanded and fortified the castle, shaping its imposing appearance.
However, it was during the Victorian era that Cardiff Castle underwent its most significant transformation.
In the 19th century, the castle's owner, the Third Marquess of Bute, commissioned renowned architect William Burges to redesign and refurbish the castle interiors, resulting in the creation of opulent and fantastical rooms that are now celebrated as some of the finest examples of High Victorian Gothic architecture in the world.
The castle remained in the Bute family until the 20th century, when it was gifted to the city of Cardiff.
⪢ The End of the Moat
In the mid-1800s, Isambard Kingdom Brunel came up with plans to divert the River Taff to the west, away from its old course around Cardiff Castle.
Having supplied the moat for over a thousand years, this move was considered to have marked the end of the defensive era of the castle.
The river now flows next to Cardiff Arms Park and the Cardiff Principality Stadium. It also allowed Cardiff Central Station to be built in an area that had previously been prone to flooding.
⪢ Air Raid Shelter to Modern-Day Attraction
Cardiff Castle also played a role in World War II, with its walls offering shelter to citizens during air raids.
Following the 4th Marquess's death, the castle and its parkland were gifted to the city of Cardiff.
For a period, it housed the National College of Music and Drama, but since 1974, it has become one of Wales' most popular tourist attractions, offering visitors a glimpse into Roman, Norman, and Victorian eras within its walls.
10 Interesting Facts About Cardiff Castle

Our Experience Rating:
Cardiff Castle
We would perhaps have given a higher rating had we had time to go inside, but even still, we would recommend a visit based on what we saw and the experience we had.
There is plenty to see here even if you do not want to spend anything, and it is a nice walk inside where you are able, and outside in Bute Park. The street with the famous animal wall too, of course.
Parking is easy to get to and is located in the heart of the city, there are plenty of other things you can do around the castle if you are going for a longer day out.
Our castle ratings have pretty high standards, and given we have been to the likes of Balmoral and Arundel, we feel that 3.5 is still pretty respectable!
Take nothing away from Cardiff Castle, it is very inspiring and wonderfully imposing! Feel free to let us know about your experience in the comments below... would you rate it higher?
