The lecture theatres are shown in black in the diagram below. The new lecture theatres (Curie, Faurre, Grégory, Lagarrigue, Painlevé, Poisson and Sauvy) are in the former Death Row (which comes out alongside the central library and restaurant). Map I shows the lecture theatres and small classrooms in the main area (marker 13). Building 7 is very important for I.T. as it contains the I.T. rooms for supervised practical work on machines, along with the I.T. Services Department (DSI), which looks after them and takes care of all the machine and network problems for the École. Maps II-III-IV provide more details on all of this and give pointers to important places, such as the login and password offices for the machines. Map III shows where to find the badge office and the teaching staff management office.
