Open Doors Day at Tredegar House

We're opening Tredegar House free of charge on 13 September, as part of Cadw's annual Open Doors event.

  • Booking not needed
  • Free event

Discover the history of the Morgan family of Tredegar House, exploring grand state rooms, 1930s bedrooms, servants' areas Below Stairs, impressive Stables and beautiful formal gardens.

Booking isn't required but we are expecting it to be busy and queues may form to enter the mansion.

Dyffryn Gardens is also holding an Open Doors day on 13 September and is only 25 minutes drive from Tredegar House - so if we are at capacity when you arrive, Dyffryn Gardens is another great option for a free day out.

Times

The basics

Accessibility

The site is mostly flat, however there are some steps in the house. We have created an alternative route for wheelchair users. The bedrooms are only accessible via stairs due to the historic nature of the house - a flip book of photographs is available for anyone who is unable to reach upstairs. Please ask a volunteer or staff member if you need assistance.

Meeting point

Please go to visitor reception before entering the house and gardens.

What to bring and wear

Dress for the Welsh weather.

Other

Only assistance dogs are allowed inside the mansion. Dogs are allowed in the gardens on a short lead. There is an off-lead area in the parkland.
