Following an action-packed summer of events, Cadw has announced the return of Open Doors – an annual festival that invites people to explore Wales’ most extraordinary, unusual, and treasured historical locations, for free.
With Wales enjoying its sunniest spring and summer on record, more people have been encouraged to spend time outdoors and visit their local heritage sites. Open Doors builds on this momentum, offering free, flexible admission to some of Wales’ most popular monuments – perfect for both planned visits and spontaneous days out while the good weather continues.
Throughout September, visitors can enjoy a range of unique events, guided tours and immersive experiences at more than 200 historic landmarks across Wales. Some of these locations are opening their doors for the very first time, giving visitors a unique opportunity to explore hidden heritage.
From castles and chapels to Roman forts and Neolithic burial chambers, a huge variety of locations are taking part. 19 of Cadw’s own iconic monuments will open their doors as part of the festival – including Laugharne Castle, Barclodiad-y-Gawres Burial Chamber, and Blaenavon Ironworks.
Funded and organised by Cadw, the Open Doors festival forms part of the wider European Heritage Days celebration, dedicated to showcasing the rich tapestry of cultures across the continent. In Wales, it opens a gateway for visitors of all ages to step into the past, immerse themselves in the nation’s dynamic heritage, and uncover the compelling stories that have helped shape its identity.
Dr Ffion Reynolds, Cadw’s Senior Heritage Events and Arts Manager, said:
“Open Doors offers a brilliant opportunity for people to discover and celebrate the richness and resilience of Wales’ historic architecture, making heritage accessible to all.
“By welcoming visitors free of charge, we’re opening pathways to experience the depth of Welsh history and culture and encouraging each person to help preserve these remarkable locations for future generations.”
A full list of participating locations can be viewed on Cadw’s website, with a selection of the festival’s highlights below:
Blaenavon Ironworks, Blaenavon
13 and 14 September, 11am-4pm
The only UNESCO World Heritage Site in south Wales, Blaenavon Ironworks is world-renowned as the first harnessed the power of steam to blow air into its huge blast furnaces in the 18th century. Visitors during Open Doors can see the dramatic remains of the furnaces, foundry cast house and the towering water balance lift.
Neath Abbey, Neath Port Talbot
27 and 28 September, 10am-11.30am and 2pm-3.30pm
Neath Abbey, founded in 1130, is one of the most impressive monastic ruins in south Wales. Once among the wealthiest abbeys in the country, its remains reflect key moments in Welsh history. For Open Doors, visitors can delve deeper into its story on extended guided tours.
The Royal Mint Experience, Llantrisant
17 September, 10am-3pm
The Royal Mint Experience is a unique visitor attraction in south Wales, offering a behind the scenes look at the craftsmanship and history of coin making. During Open Doors, visitors can embark on a guided factory tour, exploring rare coins, the art of the design, and the global significance of the Mint and even strike their own coin as a keepsake.
Oxwich Castle, Gower
6 and 7 September, 11am-4pm
As part of Open Doors, enjoy free entry to Castell Oxwich, which towers splendidly above the wide sweep of Oxwich Bay. The magnificent manor house was built by a father and son (the Mansel family) in the Tudor period, who were looking to become social climbers rather than building for defence reasons.
Insole Court, Cardiff
8, 12, 14 and 15 September, various times
Nestled in the leafy Cardiff suburb of Llandaff, Insole Court is a Grade II* listed mansion house with a rich history and a vibrant events programme.
