allow the visitor to enter inside a 19th-century research center; while the Museum of Electrical Technique, built in 2007, illustrates the history of electrical technology within five sections. Then come the Museum of Chemistry, that of Physics and the Museum of Mineralogy, founded by Lazzaro Spallanzani. Next to the Cathedral, inside the crypt of the ancient cathedral of Santa Maria del Popolo (11th century), is the Diocesan Museum of Pavia, inaugurated in 2023, which collects silverware and liturgical objects (among which a crosier in elephantine ivory carved , painted and gilded made by a Sicilian workshop by the hand of Arab craftsmen and dating back to the end of the 12th century), sculptures and paintings, such as the panel of the Madonna della Misericordia by Lorenzo Fasolo. Libraries and archives The history of the municipality of Pavia, from the tenth to the twentieth century, can be told through the amount of documentation collected within the Archivio Storico Civico (established in 1895), which also contains collections containing the archives of many aristocratic families from Pavia and of city personalities, such as Gaetano Sacchi, Benedetto Cairoli and Luigi Robecchi Bricchetti. The Archivio di Stato (founded in 1959) also collect funds from noble archives (Beccaria, Bottigella, Belcredi, Malaspina) and more, such as the Mori collection, which collects the papers of Cesare Mori. Also preserved in the archive are the acts of the notaries of Pavia (1256-1907), the maps of the Teresian Cadastre of the Pavia area (18th- 19th centuries), and the archives of the university (1341-1897), of the San Matteo Hospital (1063- 1900), the Prefecture, the Police Headquarters and the Court. Equally important is the Archivio Storico Diocesano, which houses the documentation of the diocese of Pavia since the tenth century. The Centro per gli studi sulla tradizione manoscritta di autori moderni e contemporanei (Formerly the "Research Center on the Manuscript Tradition of Modern and Contemporary Authors", also known as the "Manuscript Center"), founded by Maria Corti in 1980, is responsible for the conservation and to the study of modern and contemporary archival and bibliographic heritage. The center, among the most important of its kind in Italy, preserves collections of documentary material (manuscripts, typescripts, letters, first editions, libraries, photographs, drawings, furnishings, paintings and other objects) relating to writers, intellectuals, publishers, artists and scientists of the past two centuries. Among the archival collections preserved we remember those of Alberto Arbasino, Riccardo Bacchelli, Romano Bilenchi,
