Essentially, the main and oldest part of the Amadeus campus in Sophia Antipolis consists of two U-shaped building with the two open ends of the Us facing each other, connected by glass-enclosed walkways. Outside, an olive tree bordered alley connects the two buildings; it is from there that this photo was taken. We are looking at building B; at this point, it has four floors, numbered 1 through 4. Reflected in the glass is the other side of building B, with floors 3 through 5, a result of the fact that the site is on a hill. The main entrance and lobby are on the third floor; this is a source of considerable confusion to visitors who inevitably get lost in the many corridors that mostly look alike.  Use Google Earth to fly to N 43° 37.38', E 7° 3.51' to get a better idea of the layout.
