Discover a virtual world of Welsh heritage this September

Castell Coch Drysau Agored / Open Doors Online 2020

Get ready to explore ten of our most spectacular heritage sites like never before…

This September, we’re launching an epic collection of immersive digital experiences, fully-articulated virtual tours and 3D site excursions — allowing you to virtually visit some of your favourite historic monuments and landmarks, from the comfort of your favourite sofa.

It’s all part of a very special celebration of Wales’s built heritage and culture for 2020: Cadw’s Open Doors Online.

Powered by advanced 3D scanning technology, we’re inviting you to virtually explore the hidden depths of some of our most iconic historic sites including: Wales’s fairy-tale castle, Castell Coch, Pentre Ifan Burial Chamber and UNESCO World Heritage Site, Harlech Castle.

Our readily-accessible, digital site experiences will be available to view and explore on this webpage — with weekly themed content packages to be released in stages across the month of September.

Designed to be compatible across all devices, all you’ll need is a desk-top computer, mobile phone or VR head-set to be fully-immersed inside your selected adventure.

Choose from our below content packages to find out more about our themed virtual experiences:
Neolithic Tombs  (released on Tuesday 1 September)
Castles of the South    (released on Monday 7 September)
Abbeys and Ironworks     (released on Monday 14 September)
Castles of the North      (released on Monday 21 September)


Pssst… if you’re worried you might forget about the release date of your favourite themed content package, follow us on Facebook or Twitter for sneak peaks and thematic week reminders between 1-30 September 2020.

Please note: Cadw’s Open Doors Online, is a replacement for our annual involvement and participation in the physical Open Doors festival — which is unable to go ahead this year due to the ongoing coronavirus pandemic.

While in September, we and many other bodies and organisations in Wales usually look forward to welcoming hundreds of thousands of visitors to our country’s historic monuments, museums and hidden gems for free, it would be impractical and irresponsible for us to facilitate an event of this nature under the current climate. As such, we hope you will enjoy this alternative and unique way to engage with ten of our most spectacular heritage sites this year.

Thank you for your understanding.
