This thesis is a study of a journey in the deep mystery of the eastern harbor on the Mediterranean sea in the city of Alexandria. For Herodotus, the four major elements for civilization's development overtime are water, air, land, and fire. In this project, the effort is made to connect three of the four elements within an architectural context: "Underwater museum".

The building orientation, shape and location allow a discovery of the building elements and shape consequently while participating in the building visit. From street level, the building can be seen as a simple curved wall on the harbor facing the sea. While pursuing the passage in the journey, the building shape and components start to build the experience. Different lighting conditions, vertical and horizontal circulation methods, building form and structure are used to direct the journey starting from sky and land, through water, to underwater, then finally discovering the ruins at the seabed.
