I wish to see Wikipedia articles on a map. Explore local Wikipedia articles. The app Viki offers that feature.
NEARBY PLACES: Discover interesting Wikipedia articles about the area around your location. Or explore any other spot in the world. It’s fun with Viki’s unique map visualization.
Is there a free alternative? Maybe web based? I found with a search engine a OpenStreetMap project, but sadly not a ready-to-use product.
