Southern Europe or sometimes Mediterranean Europe is a region of the European continent. There is no clear definition of the term which can vary depending on whether geographic, cultural, linguistic or historical factors are taken into account. It is generally agreed that Spain, Portugal, Italy and Greece, more generally the Mediterranean countries of the European continent, are part of Southern Europe. The Occitania and the 3% of Turkish territory within European lands are also included in most definitions of the term.
Geographically, Southern Europe would be the south half of the landmass of Europe. This definition is relative, with no clear limits.
The Alps and Massif Central mountains constitute a physical barrier between Italy and France and the rest of Europe.
