Villa Smeraldi, Agricultural museum in San Marino, Bentivoglio, Italy

Villa Smeraldi is a rural palace complex along the Canale Navile in the San Marino hamlet of Bentivoglio. Its park holds the manor house, a neo-Gothic granary tower, the fattore's house, stables, a dovecote, an icehouse, a farmhouse, a pigsty and a gardener's house. Since 1975 the buildings house the Museo della civiltà contadina.

The villa was built in 1783 when the Counts of Zambeccari established it as their residence and shaped its agricultural character. It was later occupied by German forces during World War II and eventually transformed into a public museum dedicated to farming heritage.

The collection began with the "Gruppo della stadura", farmers and former farmers who gathered tools and household objects from the surrounding countryside as they fell out of use from the 1960s. Scholars around the chair of economic history at the University of Bologna recognised the documentary and teaching value of the gathering, which led to a community museum run by a partnership of public and private bodies. Since 2018 it has been accredited to the Regional Museum System of Emilia-Romagna.

The complex stands along the Canale Navile in the hamlet of San Marino, in the municipality of Bentivoglio. The surrounding park is public and open every day, while the museum occupies the villa, the farm outbuildings and a recent pavilion. The site is managed by the Istituzione Villa Smeraldi, created in 1998.

During the Second World War a German command under General Fridolin von Senger und Etterlin occupied the villa, using the Neo-Gothic tower for observation and the park's dense vegetation to conceal anti-aircraft positions. The Salone delle Feste on the piano nobile had been frescoed in the 19th century.
