"Cardiff Castle is one of the top visitor attractions in Wales," said Leader of Cardiff Council, Rodney Berman. "This is something we are extremely proud of in Cardiff and the opening of the new Interpretation Centre is going to enhance and improve this wonderful venue even further."
"This new facility is a great opportunity for people to learn about the history of the castle in a fun and exciting way. The facilities on offer are second-to-none and we now have a venue in Cardiff that can compete with anything else in the UK."
New hand-held multimedia guides are also on offer following the completion of the project, which run in 10 different languages. English and Welsh speakers can enjoy a commentary by BBC newsreader Huw Edwards, taking them on a self-guided tour through the Roman, Norman, Medieval and later periods of the castle's history.
A sign language option, an option for the visually impaired and children's interactive version of the tour are also included on the handsets.
