Try exploring the area around Carmignano. Here you can find Etruscan remains (Comeana and the slopes of Poggio alla Malva), roads dating from Roman times and 10th-12th century churches (Artimino e San Giusto). Carmignano and the village of Artimino, with their remains of city walls, keep and castle, are quite fascinating. Artimino itself is dominated by the Medici Villa La Ferdinanda, built by Buontalenti for Ferdinando de' Medici, son of Cosimo I.
