Quartier Latin

Roughly equivalent to the 5th arrondissement, this ancient and world-renknown part of the city is like a millenium treasure hunt or a riddle ralley for young and old alike. First challenge: find the Roman ruins and the original name for Paris. Next, on the middle ages. Where can we visit only one of three medieval demeures still standing in Paris? Now, the Renaissance. What is the unique relic to be found in the Eglise Saint Etienne du Mont? On to the Age of Reason. For what reason was the Panthéon not always a church?
