More than 2900 digitized maps from the most magnificent atlases of the Zentralbibliothek Zürich archives are waiting to be geographically located by those interested. Often ornately decorated maps from 15th-17th century splendor atlases were selected for this project. Discover how, as the world was explored, outlines of land masses on maps changed or borders shifted due to disputes. There are also imaginary islands and sea monsters in the ocean and wild animals on land to discover.
