In the prestigious complex realized by Borromini, the ex Oratorio dei Filippini in piazza dell'Orologio, has its seat the Casa delle Letterature of Rome, a civic centre completely dedicated to Italian and foreign literature of the 20th century. The Casa delle Letterature is the result of a cultural work promoted and realized by the Counsellorship of Culture: it collects, develops and improves the heritage of experiences collected in these years through the Department of Culture with the collaboration of the Ufficio Convegni Mostre Conferenze. It is, in fact, the effective seat for this sector of programmes, a centre of production of all the scientific, literary and editorial initiatives that, combining the seriousness of the scientific approach to the intention of promoting its contents, is meant for the big public. The Istituzione Biblioteche di Roma provides the permanent services of library and newspaper library specialized in Italian and foreign literature of the 20th century. The creation and management of the projects of the centre is by the Ufficio convegni-mostre-conferenze in collaboration with Institutions, Organizations, Universities, Cultural Associations both public and private, both Italian and foreigner. A precious and strong network of relations that will be strengthened and enlarged with the belief that in this cultural work an International and interdisciplinary approach is necessary.
