Sites all across Wales are opening their doors for free this week in celebration of our patron saint.

The one day event will see 16 Cadw sites, which normally charge for admission, opening their doors to the general public for free on Friday March 1.

Also marking Visit Wales' Year of Discovery, the programme will include six sites in North Wales with many others elsewhere across Wales.

Those in the region can enjoy free entry to popular places such as Conwy Castle and Caernarfon Castle , whilst the programme also includes the country's oldest surviving stone castle in Chepstow.

The scheme will also allow visitors into the historical St Davids Bishop's Palace, which is located near the site Saint David himself founded his monastery - and an ideal celebration of the Welsh patron saint.

Minister for Culture and Tourism, Lord Elis-Thomas, said: "Everyone can explore our rich history through our heritage sites in Wales as Cadw sites are free for everyone on the national day of our Patron Saint.

"From historic buildings to iconic sites, Wales is a country full of fascinating heritage and legendary monuments and you can discover the stories that they have to share for free yourselves on St Davids Day.

"Everyone will be able to continue or begin their own legendary journey into our past to uncover the stories in our castles, abbeys and other historic sites."
