That is why the fibula is so special, according to city archaeologist Cohen Stuart. In addition to the fact that the mantle pin is still almost completely intact, several symbolisms can also be found in the fibula and the gemstones come from different parts of the world. Because symbols of the Frisians, Vikings, Franks and the Middle East can be seen, the fibula also symbolizes the coming together of all these cultures in Dorestad.
