Wales’ historic attractions and hidden gems are expecting to welcome thousands of visitors this month as part of Open Doors – the largest volunteer event in the heritage sector in Wales.

This year, Cadw, the Welsh Government’s historic environment service, has for the first time both funded and organised the annual event, as part of its 30th anniversary celebrations and ongoing commitment to making heritage more accessible to the people of Wales.

Local venues taking part in the event include St David's Church near Llechryd, St Michael's Church, Tremain, Castell Henllys Iron Age Fort, and Cilgerran Castle.

Cadw is offering the first 10,000 people to register through its website free entry to its paid-admission sites over the final weekend in September, as well as hosting a packed programme of activities and events in celebration of Open Doors.

John Griffiths, Minister for Natural Resources, Culture and Sport, said: “Open Doors offers local people and visitors alike the opportunity to explore Wales’s fascinating built heritage, whether it’s through free access to sites or special events that inspire people to visit and connect with their history.”
