20 years after the Battle of Hastings, the Normans went to wales. In 1091 Robert FitzHamon built a castle called Cardiff Castle and a small village was made round it. This was an English town in an enemy Welsh land.
Owain Glyndwr attacked Cardiff in 1404 (his statue is still in CARDIFF
by the city Hall.
In the milddle ages Cardiff was a wild place with pirates. In 1608 King James I gave them a Royal Charter and in the 18th century it was a quite place with 1,500 people living around the decaying castle.
