Villa Castelbarco, Vaprio d'Adda, Italian noble residence in Vaprio d'Adda, Italy.

Villa Castelbarco is a rural palace just west of the Martesana canal and the Adda river, north of Vaprio d'Adda. Its layout follows the cloisters of the former Vallombrosan monastery, with a Baroque family chapel, a south wing holding a limonaia, and two Empire-style palazzini on the terrace esplanade.

A Vallombrosan monastery with farms and a chapel to St Carpoforo first stood here. Count Giuseppe Simonetta, who died in 1733, built a lodge and turned the monastic church into a family chapel with a polychrome marble altar. The estate passed to the Castelbarco family through the 1749 marriage of Francesca Simonetta and Count Cesare Ercole Castelbarco.

The villa's name recalls the Vallombrosan monastery that once stood here, remembered in the 19th-century name Villa Monasterolo. Since 1993 the site has been run by Ente Fiera del Barco, which works with the comune of Vaprio d'Adda through its "Ente Fiera" commission. The property is used for cultural events and private functions.

The property sits at Via Concesa 4 and welcomes visitors as an arts and culture space with regular programming throughout the year. The grounds are accessible for exploration, and guided tours help you navigate the main house and the layered spaces below.

Between 1835 and 1837 Carlo Castelbarco had themed rooms built in the basement: Egyptian, Etruscan, Roman, Oceanic and a Raphaelesque chamber, fitted with fountains and water jets. A 1907 guide records a Northern Italian sculpture he had collected there, now in the Cloisters collection of the Metropolitan Museum of Art in New York.
