The aristocratic Lanfranchi family included diplomats serving the Medici Dukes of Tuscany; for example, in the 1530s,
Albizzi Lanfranchi had been a diplomat for
Cosimo I de' Medici. The family had also owned a palace across the Arno, the
Palazzo Lanfranchi-Toscanelli. This palace was reconstructed from 1539 to 1555, uniting a series of 13th and 14th-century houses with towers into a single palace. The palace has undergone many renovations, and has housed the Museo della Grafica since 2007. ==Collection==
