All you need to know about Cardiff Castle in 25 facts.

Standing tall and proud in the heart of Cardiff, Cardiff Castle is one of Wales’ top historic attractions. Originally built by the Romans in the first century, this site of international significance has witnessed over 2,000 years of history. Read on to discover the secrets of the Castle.

  1. Cardiff Castle is located in the Castle Quarter, in the heart of Cardiff, the capital of Wales. There has been a fort on the site for almost 2,000 years. 

  2. The first Roman fort at Cardiff was probably established at the end of the 50s AD, on a strategic site that afforded easy access to the sea. It was built from stone and remains of these Roman walls can still be seen today from inside the castle grounds.

  3. The current building was built in the late 11th century, replacing the Roman fort. The castle was constructed by the Normans to support their expansion into Wales.

  4. The castle was commissioned either by William the Conqueror or by Robert Fitzhamon, and formed the heart of the medieval town of Cardiff.

  5. The twelve-sided Keep at Cardiff is known as a ‘shell’ keep because its outer walls provided a shell for smaller buildings within. Breath-taking panoramic views of the city can be seen from the top of the keep, and if you look to the north you can see as far as Castell Coch! 

  6. During Norman times the toilets hung over the castle walls, and all the waste ended up in the moat. The 'gong farmer' collected the waste during the night. 

  7. During the 19th century, the Marquess of Bute, one of Britain’s richest men, inherited the castle. Many alterations were made to the castle although he only used it a few months out of the year. It is thanks to his family that the House was transformed into a lavish and opulent palace.

  8. For nearly 900 years, Cardiff Castle’s Roman past remained hidden and forgotten. It was only discovered in 1888 when the 3rd Marquess of Bute decided to build a new tower and his workmen discovered the remains of the Roman fort.

  9. During World War 2, the castle’s tunnels were used as air raid shelters from German bombs. Almost 2,000 Cardiff residents could take shelter there. An exhibition at the castle recreates the shelters. 

  10. In 1947 the castle was given to Lord Mayor Alderman George Ferguson by the Fifth Marquess of Bute. A truly royal gesture, the Castle, along with the parkland, was presented as a gift to the people of the city. Reports at the time commented that it was “no longer Cardiff Castle but Cardiff’s Castle”.
