The Museum of Textiles and Industrial Traditions was opened with the aim of collecting, preserving and displaying objects, machinery, products and documents from the local textile industry and other local industries in Busto Arsizio. The museum also promotes cultural activities and raises awareness to help scientific and historical research into the industries.

The castle was built in the thirteenth century and lived in by the Visconti family from 1251. Part of the west facade was altered during the 17^th century, as were the interiors, which were renovated in the Baroque style with exquisitely frescoed and lavishly furnished rooms featuring 17^th century frescoes attributed to the school of Procaccini.
