Welcome to Polytechnique
A century of teaching that asks a great deal of students, and gives them the means to build.
A word from the DirectorEst. 1925 · El Harrach, Algiers
A century of engineers. The next one starts here.
Algeria’s founding school of engineering. Thirteen-plus specialties, twelve research laboratories and one demanding habit: learn to draw it, then learn to build it.
Since 1925, the École Nationale Polytechnique has trained the engineers who build the country’s water, energy and industry.

How to applyRigour, service, invention
Engineering begins with getting the calculation right. For a hundred years the school has opened new specialties as the country’s problems changed: water in 1998, data in 2020, hydrogen in 2023.
About the school
Programmes
Six domains, fourteen specialties
Every engineer starts with the same foundations, then chooses where to build.
Energy & Power
Generating, converting and carrying the energy a country runs on.
Water & Earth
Dams, treatment plants and mines: engineering with the land itself.
Structures & Machines
What stands up, what moves, and how to make it last.
Matter & Process
Transforming raw materials into fuels, metals and products.
Digital & Control
Circuits, control systems and data that make machines intelligent.
Industry & Safety
Running industrial systems well, and running them safely.
Rooted in Algiers
A national school, in the capital
In El Harrach, on the eastern side of Algiers, the school sits close to the ministries, research centres and companies its graduates go on to lead.
About the school
Research
Laboratories that answer national questions
Water, energy and resources are the country’s great engineering challenges. The school’s twelve laboratories work on them, from earthquake-resistant structures to photovoltaic conversion and water sciences.
