Get your Castle Key!   


Due to the COVID-19 lockdown, Cardiff Castle has not been able to welcome visitors. To make up for some of the lost time, from June 2020 to March 2023 anyone who signs up for a Castle Key, or renews their existing one, will now get their card valid for 39 months instead of 36 months. That's an additional 3 months of FREE entry to Cardiff Castle. We hope to see you soon.

There is an administration charge of £6.75 per Castle Key card issued.
