The Miseglia field is one of the three most important fields of the Luni region, along with Torano and Colonnata. Sited along the road that connects Carrara to Miseglia, it consists of two quarry sections called Canal Grande and Fantiscritti, formed by various types of marble, mainly vulpinite (a type of marble typical of the Apuane Alps, veined and from grey to turquoise in colour).

Already known to the Romans, as testified by several finds of ancient cutting sites, this field was again used in the Middle Ages. Among the quarries of Miseglia, the most illustrious from the historiographic viewpoint are those of Fantiscritti. This name, derived from a Roman relief of the early 3rd century A.D. depicting three divinities, is attributed to the area that lies between Bocca di Canalgrande and Mount Torrione, formed by a steep gulley particularly rich in large-grained ordinary white marble of an azure hue.

Along the road leading to the quarry of Fantiscritti, one can admire three matching bridges, known as the bridges of Vara, which were the viaducts of the old Marble Railway.
