The MAP - Plastic Art Museum is located in Castiglione Olona in the province of Varese and was inaugurated in 2004. The Museum was set up in the Palazzo dei Castiglioni in Monteruzzo, whose rooms have entirely preserved 14th-century frescoes. The permanent collection consists of works of art from plastic materials created by Count Ludovico Castiglioni and his cousin Franco Mazzucchelli. Between 1969 and 1973 they set up a research laboratory equipped with technologies and personnel from the Mazzucchelli Celluloide factory. The factory is considered the most important in Italy for the production and processing of plastic material. There are many artists who collaborated on the project, among which we remember: Carla Accardi, Giacomo Balla, Man Ray and Filippo Avalle. Very interesting is the possibility of visiting the Museum walking between modern and contemporary art in an elegant architectural setting.
