Open Doors is returning for September.

Organised by Cadw, which is celebrating its 40th anniversary this year, Open Doors is an annual festival giving everyone access to some of Wales’ most extraordinary and treasured historical locations.

Throughout September, more than 200 historic landmarks across Wales will host a range of free events, guided tours, and immersive experiences, some for the very first time.

These are the Pembroke Dock Heritage Centre, Paterchurch, a medieval fortified tower, and Pembroke Dock Ginkgo Tree, which was planted there in the 19th century, as a gift from a representative of the Japanese Naval fleet. Booking is required.

Ffion Reynolds, Cadw’s heritage and events manager, said: “Open Doors is a chance for us to celebrate the diversity and resilience of Wales’ historic architecture in a way that’s accessible to all.

“By offering free access to these locations, we hope everyone will have the opportunity to experience the depth of our country’s history and culture and play a role in preserving these places for future generations.
