On Saturday 19 August, as part of National Heritage Week 2017, Andrew McClelland gave a Twitter talk about the growing importance of digital public participation in heritage. The talk formally launched the #MyValuedPlaces exercise, a map-based survey seeking public views on valued places in the cross-border cultural landscape of North West Ireland. #MyValuedPlaces is one of three cases being progressed as part of the REINVENT Project  focused on the Derry City & Strabane District and Donegal County Council areas. The talk is available to view on Storify.
