As it stood in 1350

What Castle of Legnano looked like in its prime.

A compact, rectangular brick castle standing on a river island, dominated by a tall, square gatehouse/keep at the centre with a large arched wooden entrance. Low crenellated brick curtain walls extend left and right to two shorter, cylindrical corner towers with tiled conical roofs; inner ranges of lower stone-and-brick buildings and a small church roofline sit just behind the wall. Walls show narrow arrow slits and walked battlements; the whole complex presents red‑brown masonry, terracotta roof tiles and a tree-lined river setting. At its prime the fabric is complete and roofed.

Its story

The story of Castle of Legnano.

The Visconti Castle of Legnano, known since the 13th century as the castle of San Giorgio, stands on a natural island in the Olona River south of the town. The island, formed by the Olona and its secondary branch the Olonella, was called the "Braida Arcivescovile" because it belonged to the archdiocese of Milan, and the site began not as a fortress but as the convent of San Giorgio.

The convent's monks suffered harassment from powerful locals, "magnates et potentes", settled on lands bordering the archbishopric's. After Archbishop Leone da Perego died in 1257, the Della Torre family, the most important noble opponents of archiepiscopal supremacy over Milan's government, eventually imposed themselves in the struggle for the city's lordship, began occupying archiepiscopal properties in the Milanese countryside, and took possession of the convent of San Giorgio for its strategic location while the see stood vacant.

The complex was later transformed into a Visconti stronghold, fortifications clustered where the Visconti owned most real estate, and the family's arable land stretched beyond Legnano to Canegrate, San Vittore Olona, Villa Cortese and Dairago. Such castles also served as summer retreats from the heat and narrow streets of Milan. The fortified complex comprises a gatehouse, curtain walls and multiple towers surrounding internal buildings, including the convent church.
