Sagnlandet Lejre is an archaeological open-air museum near the town of Lejre, Denmark. It represents the Stone Age, Bronze Age, Iron Age, Viking Age, smallholdings of the 18th century, and some medieval crafts. It's not a zoological institution per se, and thus I didn't give it its own folder, but it does display 10 species of animal (mostly domestics) where it makes sense in the historical context.
