Fodor's Expert Review Museo dell'Opificio delle Pietre Dure
Adjacent to this fascinating small museum is an opificio, or workshop, that Ferdinand I established in 1588 to train craftsmen in the art of working with precious and semiprecious stones and marble (pietre dure means hard stones). Four hundred–plus years later, the workshop is renowned as a center for the restoration of mosaics and inlays in semiprecious stones. The museum is highly informative and includes some magnificent late-Renaissance examples of this highly specialized and beautiful craft. If you're going to the Uffizi, do keep your ticket, as entrance to this museum is free.
