In this article the author has attempted to distinguish between the two concepts of -landscape— and —territoriality- by showing that they are not based on the same epistemological fundaments. The concept of landscape originates from what is - seen -(« the seen »), whereas the concept of territoriality originates from what is — lived -(« the lived »). He has endeavoured to make this distinction through a semiological approach. Classical geographers have mainly explored the geography of landscape while today geographers are trying to introduce a geography of territoriality. Territoriality could be defined as the complete range of relationships an individual is led to establish with his environment (sensu lato) as a member of a community. The geography of territoriality is emerging and tends to complete, if not to replace, the geography of landscape.
