History
Originally founded as the Leicester School of Art in 1870, the university has evolved through many incarnations including the Leicester Colleges of Art and Technology and Leicester Polytechnic. Leicester Polytechnic officially became De Montfort University on 26 June 1992.
The building is over 120 years old and has seen many changes in its time. It was formally occupied by banking group Alliance & Leicester PLC as their main headquarters. It now forms part of the vast De Montfort University campus.
