Frequently Asked Questions


Early History

Romans & Normans

Somewhere around 55 CE, the very first fort on the current Cardiff Castle’s grounds was built. Most likely occupied until 80 CE, it was followed up by another couple of smaller forts until the late 3rd century when a pirate threat started threatening the Romans’ hold on the area. At that time, the castle/fort site would have been directly overlooking the harbor instead of the center of town as it is today. The fort would have been occupied for at least a century until the Romans began departing the area, with no major signs of habitation uncovered between then and the Norman invasion.

A moat-&-bailey style castle wouldn’t be raised for another 800 years until at least a couple of decades after the Norman invaders began pushing into Wales in the 1060s. Nonetheless, the very first “castle” was most likely still a timber construction, with the outer walls being built on the collapsed remains of the Roman fort. The surrounding lands were split into “knights’ fees”, given out on the condition that the knights maintain houses in the castle’s outer bailey and come to the castle’s defense when needed. Cardiff Castle at this time was a Marcher Lord, meaning that in return for protecting the line between more rural Wales (still largely under Welsh control) & Norman-dominated England, the resident lord of the castle enjoyed special privileges and a certain amount of freedom from the English Crown.

Host to the Royal Extras

Of course, that also meant the crown tended to appoint particularly loyal lords, such as Henry I’s appointment of his own (illegitimate) son, Robert of Gloucester, in 1122. This is probably when Cardiff Castle took form in stone, with increased defenses built in as well. The building project is hypothesized to have started in response to the Welsh uprising in 1136. Because of its prominent location, Cardiff Castle continued to play a key role throughout the next centuries in the struggles between the Welsh and Normans, who left their mark in the form of castles all across England.

Robert of Gloucester passed the castle to his son, William Fitz Robert. William was taken hostage by Welshman Ifor Bach for a time in 1158, followed by another attack in 1183. The next year, the town walls of Cardiff had been built with the West Gate constructed in the gap between the castle and river (which had already moved some since the Roman period).

When Fitz Robert died in 1183 leaving only three daughters, Henry II made an exception to the typical inheritance customs of the time. He allowed William’s daughter Isabel to inherit the castle and lands. It seemed like a forward-thinking move … until Henry II married Isabel to his youngest son Prince John. He promptly took control of the castle and lands, retaining control after he divorced Isabel. Isabel remarried to Geoffrey de Mandeville and her inheritance passed to his control. When Isabel died childless three years later, the castle passed to her nephew, Gilbert de Claire. The de Claire family reinforced the castle defenses–including building the Black Tower–as they faced off with the native Welsh prince Llywelyn ap Gruffudd. This was long before the title Prince of Wales was an English inheritance.

Six Hundred Years

From the de Claires, Cardiff Castle passed through a number of influential families. The Despencers, the Beauchamps, the Nevilles, the Tudors, the Windsors (long before they became a reigning house), and finally, the Butes each made their mark on the castle.

As a side note to the castle’s history but of note overall, Cardiff Castle passed between the Nevilles and the Tudors during the War of the Roses. It never actually came into militant importance during this time. Nonetheless, it was the Tudors’ ascension to the English throne from their Welsh roots that helped ease Welsh-English relations. It also instigated the use of the “Prince of Wales” title for the English crown’s heir.

After six hundred years of apparent stability, the 1st Marquess of Bute had the main range renovated into a Georgian-style manor house. His son, the 2nd Marquess of Bute, made Cardiff a notable coal exporter and built a fortune in the process. In 1866, under John, 3rd Marquess of Bute that legacy was put to good use overhauling the manor again. Stained glass windows, murals, marble, ornate carvings, and opulent gilding created a fanciful Neo-Gothic castle. The project was completed by the 4th Marquess.

Current Times

The 4th Marquess of Bute also oversaw Cardiff Castle during WWII, when it again played the part of a defensive fortress–albeit slightly differently than the medieval style. Tunnels built into the walls of Cardiff Castle were used as bomb shelters. They could host around 2,000 civilians when the sirens sounded.

After the 4th Marquess’ death, the Bute family passed the castle to the City of Cardiff. Through the mid-20th century, Wales’ National College of Music and Drama resided at the castle. It was opened as a tourist attraction in 1974.
