The castle is located in central Cardiff, next to Bute Park. It’s likely that the Roman Fort was established in Cardiff at the end of the 50s AD, the remains of the Roman wall can be seen today. After the Norman invasion, the castle’s keep was built on the site of the Roman fort. The castle belonged to different people over the years. Then, in 1766, the Castle was transferred by marriage to the Bute family. Following the death of the fourth Marquess of Bute, the family decided to give the Castle and many of its parklands to the city of Cardiff. The castle is now popular for visitors.
