There's an interesting story on BBC about ex-villages - the publisher Collins would like to create a digital archive about these villages. Do you have a genealogical interest in a place that no longer exists? Some of these were abandoned relatively recently as a result of military involvement, so now is the time to ensure memories and information about those places aren't lost.
