Municipality of the Franciacorta area, on the slopes of Mount Alto, Adro has ancient origins, evidenced by the Neolithic age findings found in the district of Torbiato, as well as several tombs, complete with funeral ornaments of the late Roman and Lombard domination periods. The name has uncertain origins: it may derive both from the Latin "ater" (black, dark), or from "acer" for the presence of maple trees. The town is mentioned, for the first time, in a document of 882, in which the Monastery of San Salvatore in Brescia received the name of Atro.
It boasts an ancient farming tradition and its territory is famous for the production of excellent grapes.
Among the architectural jewels of the town, worth of mention: the XVII century Palazzo Dandolo Bargnani, severe and elegant, today the Town hall. The building belonged to the Dandolo family and inside it preserves documents and works of art of the family's heritage, including a painting of Pitocchetto. In the chapel, that features an elliptical plan, is kept an altarpiece attributed to the artist Celesti.
Other important monuments are: the XVII century Parish Church of Saint John the Baptist with its Baroque decorations and woodworks of Fantoni di Rovetta, frescoes of Teos, a wooden choir, an altarpiece by Antonio Cifrondi and altars in polychrome marbles; the XV century Mother church of Santa Maria Assunta, today the church of the cemetery; the Church of Santa Maria in Favento, built in the Middle Ages, and the Sanctuary of the Madonna della Neve.
