AS part of Cadw’s Open Doors heritage festival, more than 100 landmarks across North Wales will offer visitors free entry this September.

The ever-popular festival of Wales’ built heritage runs throughout September and will encourage North Wales residents and visitors alike to explore some of the country’s lesser-known sites ― several of which are usually closed to the public.

Among the sites, landmarks and hidden gems to feature in the festival are Penrhyn Castle in Bangor, Segontium Roman Fort in Caernarfon and Plas Newydd on Anglesey.

Six staffed Cadw sites, including the medieval Denbigh Castle, will be offering members of the public free site access during the month-long heritage celebration.

Meanwhile, 11 of Cadw’s unstaffed sites, many of which are usually closed to the public, will also offer guided tours for free on select dates in September ― including Barclodiad-y-Gawres Burial Chamber on Anglesey.

Non-Cadw sites, such as Bodorgan Hall, are also offering free guided tours, giving visitors the opportunity to explore sites such as this 18th century neo-classical mansion.

Gwilym Hughes, Head of Cadw and Deputy Director in Welsh Government, said: “We warmly welcome the return of Open Doors ― Wales’ annual contribution to European Heritage Days ― running throughout September.

“Not only is it a celebration of the rich and fascinating history Wales has to offer, but an opportunity for more people than ever before to inspire a life-long love of history and culture ― especially our younger generations.

“And by opening these sites for free, we hope to provide an equal opportunity for all to explore, enjoy and uncover the untold stories of Welsh history on their doorstep.”

Pre-booking for Cadw sites, whether staffed or unstaffed, is not necessary – walk-ins are encouraged, with a chance to join complimentary guided tours at select sites.
