“America’s continental divide is known worldwide. However, nobody ever considers the presence of a European’s continental divide. While for America the subdivision seems more obvious (Atlantic and Pacific coasts, though nobody ever talks about the Pacific and Arctic divide!), in Europe the subdivision might be between the two largest water bodies bordering the subcontinent: Atlantic and Mediterranean Europe.”
“This physical (hence, objective) subdivision is interesting per se, since some countries considered Mediterranean actually are mostly looking towards the Atlantic (Portugal fully and Spain mostly), others considered central European actually lie fully within the Mediterranean basin, such as Hungary, or mostly (Slovenia, Austria). Even Germany has a big fraction of its area within the Mediterranean watershed!”
