Who commissioned Leonardo da Vinci’s revolving bridge design?

Ludovico Sforza commissioned Leonardo da Vinci’s revolving bridge design.

Leonardo worked in Milan for Ludovico Sforza, the city’s powerful duke and patron, during the late 15th century. Among the military and engineering projects associated with this period was a bridge designed to swing or rotate into position and then be removed quickly.

The concept addressed a practical military problem. A portable bridge could help troops cross an obstacle while allowing defenders to dismantle or relocate it rapidly. Leonardo’s drawings emphasized efficient construction and compact handling rather than merely decorative architecture.

Ludovico Sforza is also known as Ludovico il Moro. He supported Leonardo’s work in painting, engineering, architecture, and scientific observation, making Milan the central setting for many of Leonardo’s most famous designs.
