After an incredible summer of cultural events, from the Olympics to the Euros, Cadw has today announced the return of Open Doors – an annual festival that gives everyone access to 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. This year’s Open Doors event is especially poignant as Cadw celebrates its 40th anniversary with an exciting year of activities.
From castles and churches to clock towers and ancient burial chambers, and even Dylan Thomas’ Boat house, there are a huge range of locations taking part. Twenty two iconic Cadw monuments, including Denbigh Castle, Segontium Roman Fort, Harlech Castle and Strata Florida Abbey, will welcome visitors free of charge, inviting them to explore these remarkable places.
Open Doors is part of the broader European Heritage Day festival, aimed at highlighting the rich cultural diversity across Europe. This initiative offers a unique opportunity for people of all ages to connect with history, experience Wales’ vibrant heritage, and discover the captivating stories that have shaped the nation.
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.
“This year also marks a significant milestone for Cadw as it marks its 40thanniversary; it’s great to host the festival as part of the wider celebrations throughout the year.”
