Jan S. Krogh's Geosite: France – Monaco (FRMC)

Monaco shares a 4.4 km dry boundary with France. Also her territorial waters are only shared with France.  The state language is French, but due to that the traditional national language is Monegasque, the entry signs to the country, as well as many street signs, are bilanguaged.  The Monegasque boundary research is very difficult due to the lack of detailed topographic maps.  The only available recently published maps we have available are tourist maps.

In this report we will focus on three areas with modern markers on the Franco- Monegasque border; at Boulevard Charles-III (FRMC1), Boulevard du Jardin-Exotique (FRMC2) and Place Antonine-Repaire (FRMC3).  Furthermore we will study an ordinary border area (FRMC4). These modern markers are no traditional border stones, but more one road stone and some kind of touristic markers. The  Jardin-Exotique column is the closest we find to a traditional international border marker. In general the Franco-Monegasque boundary's principal characteristic is the almost total absence of any kind of demarcation. Even policemen (French citizens in Monegasque uniforms) on duty at the border do not know exactly where the border goes.
