VEWA e. V. is a German nonprofit association dedicated to the preservation of heritage and nature at the former Westwall, the historic line of fortifications in western Germany.

Its work combines conservation, research, documentation, and public education, treating the bunkers and related structures as both cultural heritage and places with environmental considerations. The association shares information through articles, a fortification blog, frequently asked questions, an atlas of western fortifications, monitoring resources, a catalogue of standard designs and construction forms, and geographic information data. It also documents structures in its care and supports efforts to record their plans, history, types, and current condition so that heritage can be considered in planning and conservation decisions.

VEWA publishes guidance and positions on topics such as bunker preservation and site safety, and highlights practical approaches to maintaining access controls while protecting structures and visitors. Public engagement includes information panels, guided visits, and opportunities to contribute to research and documentation
