The Discovery Programme, a national archaeological research body supported by the Heritage Council, has been publishing some fantastic 3D models for the past few years which can be viewed on their user page with Sketchfab. There are some wonderfully detailed modelling samples there, from Iron Age fortresses to Medieval churches, which can be viewed on a desktop, mobile or VR (virtual reality) device. I highly recommend that you take a look.
thanks, a fantastic site. i’ve been to most of these places but this is almost as good as a visit
+1 – this is a genuinely great.
