We built Fornland — a React + TypeScript app using MapLibre GL that pulls live data from national heritage databases across Denmark, Norway, Sweden, Finland, Iceland, Greenland, and the Faroe Islands. Sources include WFS services (kulturarv.dk, Fornsök, Kulturminnesøk), ArcGIS REST APIs, Wikidata SPARQL, and OSM Overpass. 15 layers covering everything from Bronze Age rock art to Viking runestones. Enriched with Wikipedia, Europeana, and Wikimedia Commons. Free, no login, no tracking.

Super cool. Great collection in a clear visual setup. (I love map interfaces).

Quick note:

I went to utmost top of the map and clicked the (2) near Greenland. Quite clunky to actually get there as the map moved in and out. Selecting "Kap Erik Bunch" led me to the ArcGIS REST Services Directory with errors:

Unable to complete operation. Unable to perform query operation

Still cool. Just sharing some user testing :)
