The current Villa Besozzi Casati Visconti di San Vito was built by the Besozzis, probably in the third quarter of the 17th century, reforming a pre-existing medieval stronghold, purchased during the previous century from the monastery of Sant'Ambrogio in Milan. An ante quem term for the location of the architectural intervention is, in fact, constituted by the date 1678, reported in the frescoed decoration of one of the rooms on the first floor. On 18 October 1798, the villa was sold to Gaspare Casati, together with all the real estate and land assets owned in Cologno by Count Antonio Besozzi, and, at the end of the following century, it came to the Marquises Visconti of San Vito, following the marriage - celebrated on 9 September 1891 - between Roberto Visconti of San Vito and Anna, the last member of the Casati family. It was left to the Municipality of Cologno Monzese to which it still belongs, in 1968. Villa Casati is the prestigious current headquarters of the Municipality of Cologno Monzese. The renovation of the south wing of Villa Casati expanded the municipal headquarters: the secretariat, the mayor, the municipal council and the municipal council were located there. While the custodians and farmers of the Villa still lived in the north wing until 1974. From 1988 to 1990 the north wing of the Villa was renovated. The ground floor was occupied by the Culture, Sport and Leisure offices, the Municipal Information Service and the Municipal Police. In 1992 the entire second floor and the new building in via Sormani became home to the Civic Library.
