over by the University of San Marcos. During the government of Ramón Castilla, San Marcos was officially empowered by the president to approve new universities and control the newly created ones. Throughout the 19th century, the premises of the University of San Marcos abandoned its academic functions, becoming more regular as a space for meetings of the Chamber of Deputies and the Congress of the Republic. The absence of care and the partial abandonment of their university functions led to a gradual deterioration of their environments. It is in this context of the end of the 19th century that the university completely donates its premises to the then still young Congress of the Republic of Peru.

During the War of the Pacific and specifically during the occupation of Lima by Chilean troops, art and cultural objects and assets were taken from the university in order to be taken to Chile by sea.
