What is Archwilio?

Archwilio provides public access to the Historic Environment Records (HERs) for Wales. It includes (or provides access to) information on tens of thousands of historic sites and pieces of investigative work. The HERs are maintained on behalf of the Welsh Ministers by the regional Welsh Archaeological Trusts and in fulfilment of the requirements of the Historic Environment (Wales) Act 2016.
