Some well-know Boston districts were unstructured in the public image. The West End and North End were internally undifferentiated for many people who recognized these regions. Even more often, thematically vivid districts such as the market area seemed confusingly shapeless, both externally and internally. The physical sensations of the market activity are unforgettable. Faneuil Hall and its associations reinforce them. Yet the area is shapeless and sprawling, divided by the central Artery, and hampered by the two activity center which vie for dominance: Faneuil Hall and Haymarket Square. Dock Square is spatially chaotic. The connection to other areas are either obscure or disrupted by the Artery. Thus the markets district simply floated in most images. Instead of fulfilling its potential role as a mosaic link at the head of the Boston peninsula, as does the Common farther down, the district, while distinctive, acted only as a chaotic barrier zone. Beacon Hill, on the other hand, was very highly structured, with internal sub-regions, a node at Louisburg Square, various landmarks, and a configuration of paths.
