Doors and Other Passages: a Semiotics of Space Dalila Honorato Abstract The intention in this chapter is to explore the various meanings of doors and other places of passage by referring not only to a mechanism that opens and closes but to a net of different interior images within the universal concept of The Door. In its initial form, the door might have had its shape improvised by use of simple material without the stability of material that characterizes a modern door. Today’s idea of a door seems to have its origin at the exact moment humans abandon nomadic life and the round shelters that characterize food collectors’ communities (such as a tent, a cave or an igloo), to become specialized in a labor activity and permanently inhabit a specific place within a square house.

Key Words: Doors, gates, portals, arches, passages, locks, doorknocker, teleportation, enclosure, psychogeography. ***** 1.
