House of the Jesuits (, later Lycée Charlemagne), and the Collège des Quatre-Nations (). The latter building, however, was repurposed in 1801 for artistic training, and its secondary school was relocated to the adjacent to Louis-le-Grand then known as the Prytanée (), then merged into it in 1804. In 1803, Napoleon created the Lycée Condorcet in the former , and in 1820, another new took the premises of the former , now the Lycée Saint-Louis. Louis-le-Grand was thus one of only five public in Paris for most of the 19th century, until Jules Ferry's reforms greatly expanded secondary education in the 1880s. Bordering Louis-le-Grand to the north, some of the buildings of the former were partly used by the École normale from 1810 to 1814 and again from 1826 to 1847, after which it moved to its present campus designed by architect Alphonse de Gisors on . Others parts of the Plessis complex were temporarily awarded to the Paris University's Faculty of Letters and a section of the Faculty of Law, but were demolished in 1833 as they had become derelict. During the early Second Republic, an opened in July 1848 on the École Normale's former location, promoted by politician Hippolyte Carnot, but it met overwhelming opposition and ceased operating after about six months. Louis-le-Grand eventually acquired the remaining Plessis buildings in May 1849 and tore them down in 1864. Meanwhile in 1822, Louis-le-Grand had expanded southwards by taking over the former from the University. Louis-le-Grand's main buildings themselves were in an increasingly dilapidated state, implying danger for the students. From the 1840s onwards multiple attempts were made to start their reconstructions, but faltered for several decades. In the mid-1860s, Georges-Eugène Haussmann promoted a project to move Louis-le-Grand to the premises of the on , but that initiative was short-lived and the complex on rue de Sèvres was instead repurposed a decade later as . Eventually, Louis-le-Grand was almost entirely reconstructed between 1885 and 1898 on a design by architect , on a complex schedule so that teaching activities could continue during the works, and at a record high cost. Le Coeur's design only preserved the northern and southern sides of the inner court (now ) from the earlier college facilities. He created two vast courtyards to the north () and south () of that central space, with multiple levels of classrooms connected by airy arcaded corridors. That rebuilding project
