During the summer of 2020 we have been working with Cadw to deliver their Open Doors programme as a digital heritage festival online. Get ready to explore ten of Wales' most spectacular heritage sites as immersive digital experiences and fully-articulated virtual tours. We’re inviting you to virtually explore the hidden depths of some of the most iconic historic sites including: Wales’s fairy-tale castle, Castell Coch, Pentre Ifan Burial Chamber and UNESCO World Heritage Site, Harlech Castle. Blaenavon Ironworks is the virtual tour featured on this post.
