Open Doors is a Europe-wide festival celebrating heritage and architecture which takes place throughout September as part of European Heritage Days. Blaenau Gwent is inviting local residents and visitors alike to discover the area's rich heritage through a programme of special visits and events. Participants will have the opportunity to learn more about the history that has shaped our towns, valleys and communities, and their influence on the wider world.
Open Doors gives everyone the chance to explore historic buildings and sites free of charge, including many that are not normally open to the general public.
The festival kicks off on Saturday 5 September 2026, when the famous Tredegar Town Clock opens its teeny weeny door to visitors from 10am to 12.30pm. At 168 years old, the clock is the tallest freestanding iron clock in the UK, standing at 72 feet (22 metres). Visitors can learn more about its fascinating history and climb a series of ladders to the top.
To avoid disappointment, visitors are encouraged to book online through the Eventbrite ticketing website. Tickets are free but are the only way to guarantee a visit.
On 6 September, Llanhilleth Miners Institute will open its doors from 11am to 3pm. The Grade II listed building continues to thrive as a community centre, event venue and site of historical interest. Opened in 1906, the Institute celebrates its 120th anniversary in 2026 and has marked the milestone with a programme of special events throughout the year.
The building retains many of its original features and spans three floors. The impressive Ithel Hall serves as a stunning centrepiece, while the Heritage Centre offers visitors the opportunity to explore artefacts, photographs and records relating to the Institute and the local community. Visitors will be able to take part in free guided tours, enjoy special exhibitions and view the Institute's celebration mural.
Later the same day, St Illtyd's Church in Abertillery will open to the public from 2.30pm to 4.30pm. St Illtyd's is widely regarded as the oldest surviving building in Blaenau Gwent. The large, roughly circular churchyard reflects its Celtic origins, while the earliest written reference to the church appears in a poem dating from the ninth or tenth century in Llyfr Du Caerfyrddin (The Black Book of Carmarthen).
The ancient chancel, striking tower and simple whitewashed interior evoke the austerity and simplicity of its monastic origins. The churchyard is maintained as a wildflower meadow and offers panoramic views across the Ebbw Valleys.
The church is cared for by a dedicated group of volunteers who are keen to share its history with visitors. The graveyard has been fully recorded, providing a valuable resource for family history research.
Cllr John Morgan, Blaenau Gwent Council's Cabinet Member for Economy and Place, said:
"The Open Doors Festival is a fantastic opportunity to explore some of Blaenau Gwent's most fascinating historic sites, many of which are not normally open to the public. This year's programme offers visitors the chance to discover our oldest standing building, climb our iconic Town Clock and experience the unique heritage of Llanhilleth Miners Institute. We look forward to welcoming residents and visitors to these special events."
European Heritage Days is an initiative of the Council of Europe. In Wales, the event is coordinated by Cadw, while partner organisations arrange parallel events in England and Scotland. Since its launch in 1991, the initiative has attracted millions of visitors to participating sites across Europe each year.
