1594. Boulevards (Boulevard, Fr., or round work; a bulwark, or great bastion, or rampart, generally round). Many of the continental cities have a species of equestrian promenade within their boundaries, which is deserving of imitation. These are broad roads, accompanied by rows of trees, near the margin of the city, originally formed on the ramparts, or surrounding fortifications, and completely encircling it. They are highly interesting promenades, especially to a stranger, to whom they give an idea of the topography and most remarkable points of the scene in the most agreeable manner. The boulevards at Paris, Vienna, and Moscow, are particularly to be admired in these respects.
