[6] Overall, its campus includes over 25 buildings in Paris, such as the Centre Pierre Mendès France ("Tolbiac"), the Maison des Sciences Économiques, among others.

Students were crammed into overcrowded classrooms and lecture theatres, and the teaching staff, who were too few in number, did not have the resources to monitor and supervise them properly.

The decentralisation of university campuses and centres in and around the capital was mainly the work of the Fifth French Republic in the early years of its existence.

As this reform had not been negotiated with all the interested parties, it was rejected by students in an unfavourable political and social climate, and provoked a veritable insurrection in faculties in Paris and the other regions.

At the instigation of professors François Luchaire (public law), Henri Bartoli (economics) and Hélène Ahrweiler (humanities), the three official co-founders of the university, the Paris 1 "Panthéon-Sorbonne" University was created in 1971 from the merger of part of the Faculty of Law and Economics (Panthéon) and part of the Faculty of Arts and Humanities (Sorbonne).

At the end of the 19th century, when the Sorbonne was undergoing major reforms, an extension was planned for the Panthéon Centre, designed by Louis-Ernest Lheureux.

The construction of the Cujas wing, an 8-storey building on rue Cujas designed by the architect Jacques Becmeur, comprising a car park, an amphitheater and 4 floors of offices, is connected to the historic buildings by a monumental staircase which was later decorated by the students of the Sorbonne Fine Arts Department (UFR d'Arts Plastiques).

The institute was designed to bring together in a single building the collections, teaching and research in geography, hitherto divided between the faculties of arts and sciences.

The building offers in particular to the gaze of walkers, at the base of the large arcades, a frieze formed of terracotta bas-reliefs reproducing famous works of world art (Parthenon, Ara Pacis Augustae, etc.).

The syncretism desired by Paul Bigot gives the Institute of Art and Archeology an educational virtue that resonates with the function of the building.

Inside, the entrance vestibule, the amphitheater and the large reading room of the library, which occupies the heart of the building, have retained their volumes, but, on the floors, the galleries which housed the collections The heritage structures constituted in the Sorbonne and Paul Bigot's plan of Rome were abolished in the 1970s in favor of a partitioning of spaces into classrooms and teachers' offices, following the massification of higher education.

Matured since 2011, the project to create a new law campus was entrusted in 2014 to the Public Establishment for University Development of the Ile de France region (EPAURIF) with a contracting authority mandate.

The architectural challenge of the project was to preserve this heritage, testimony of the urban history of this district by touching it as little as possible, while developing it in an optimal way.

In addition to the three buildings on the Lourcine block, the current René-Cassin center has been attached to the new site to give birth to the Port-Royal Campus from the start of the 2019 academic year.

Renamed in 1983 in honor of the French politician Pierre Mendès France, the Center Pierre-Mendès-France was built in the context of post-68 university programs and the urban renewal of the Italy XIII sector undertaken since 1964.

The site – a cramped triangular plot of 7,500 m2 hitherto occupied by a deposit of cobblestones – led to the original and ambitious choice of vertical development, which is quite unusual in terms of university architecture.

The School has 17 specialized libraries, among the richest in the world in their scientific fields, for books and document collections and for access to digital holdings.

Located in the heart of the 15th arrondissement, at 47 rue des Bergers, in a building of more than 7000 square meters entirely dedicated to it - the Saint Charles Centre - the EAS welcomes nearly 3000 students.

It has a university library specifically dedicated to art and creation, an amphitheater, a contemporary art gallery, classrooms for theoretical courses, workshops for artistic practices (sculpture, painting, ceramics, silk-screen printing, engraving, a silver and digital photography laboratory, a Fab Lab... ), an office for the loan of audiovisual material, computer rooms, editing rooms, etc.

[27] More than 22.84% of students accepted by the university having received highest honors ("mention très bien") in high school during the 2019 session (first of France).

[29] Every year around 400 PhD theses are defended and 1,700 pre-PhD post-graduate degrees are awarded in 74 subjects divided between 15 graduate schools.

These exchanges revolve around international networks such as Europaeum which bring together Oxford, London, Bologna, Bonn, Geneva, Helsinki, Leiden and Prague.

The consortia are responsible for major international projects in Bucharest, Buenos Aires, Cairo, Istanbul (Galatasaray), and Moscow.

African students are joined by increasing numbers from Asia and America, and take part in specific programs organised in conjunction with universities across the world.
