Laumellum was a Roman
mansio (a stopping place on a road) on the way of Via Regina, the main road connecting
Ticinum (now
Pavia) with Turin along the way of the Galliae. The archeological excavations made by the Universities of Pavia and of London during the latest years, brought to light inscriptions, cemeteries of the Imperial period, as well as ruins of fortifications and an entrance door in the boundary wall. Laumellum was perhaps a pre-Roman center of the
Ligures. During the
Lombard domination (569-774), Lomello began to know a considerable prosperity. This was the place where Queen
Theodolinda, widow of Authari, married
Agilulf, Duke of Turin, in 590. Queen Gundeberga, daughter of Theodolinda and wife of Arioald, after being charged with the betrayal of her husband, was imprisoned in a tower in 629 and released after three years, thanks to the first "Judgement of God" ever celebrated in Italy. In the
Carolingian period, it was the place of a comitatus and in 1024 the fortress of Lomello was elected to the residence of the Palatine Counts while, in the same years, the basilica of Santa Maria Maggiore was built as a mark of wealth and power. The
commune of Pavia defeated the Counts in the 1140s and captured Lomello, owning it until 1360, when Lomello came under the domination of the
Visconti, who were followed, from 1450 to 1535, by the
Sforza.
Francesco Sforza assigned the County of Lomello to the
Crivelli family, who held it continuously until 1760. ==Main sights==
