The grid also makes a complex place instantly navigable. This isn’t a trivial benefit. Cities like Berlin and London, historic agglomerations of villages, include vast nowhere stretches, and they sprawl in ways that discourage easy comprehension and walking. An epicenter of diversity, Manhattan by contrast invites long walks, because walkers can judge distances easily and always know where they are. The grid binds the island just as New Yorkers are bound by a shared identity.
