Leghorn is intersected by canals, sufficiently so to have been sometimes called a "Little Venice," and has been fortified, but as the defenses belong to the system of Vauban, they add little to either the interest or the picturesqueness of the place. Parts of the walls and the citadel remain, the latter being enclosed by a broad water-ditch. The principal street has some good shops, and there are two fairly large piazzas; in one, bearing the name of Carlo Alberto, are statues of heroic size to the last Grand Duke and to his predecessor. The inscription on the latter is highly flattering; but that on the former states that the citizens had come to the conclusion that the continuance of the Austro-Lorenese dynasty was incompatible with the good order and happiness of Tuscany, and had accordingly voted union with Italy. The other piazza now bears Victor Emmanuel's name; in it are a building which formerly was a royal palace, the town hall, and the cathedral; the last a fair-sized church, but a rather plain specimen of the Renaissance style, with some handsome columns of real marble and a large amount of imitation, painted to match. There are also some remains of the old fortifications, though they are not so very old, by the side of the inner or original harbor. As this in course of time proved too shallow for vessels of modern bulk, the Porto Nuovo, or outer harbor, was begun nearly fifty years since, and is protected from the waves by a semicircular mole. Among the other lions of the place, and they are all very small, is a statue of Duke Ferdinand I., one of the founders of Leghorn, with four Turkish slaves about the pedestal. The commerce of Leghorn chiefly consists of grain, cotton, wool, and silk, and is carried on mainly with the eastern ports of the Mediterranean. There is also an important shipbuilding establishment. It has, however, one link of interest with English literature, for in the Protestant cemetery was buried Tobias Smollet. There is a pleasant public walk by the sea margin outside the town, from where distant views of Elba and other islands are obtained.
