Today in the studio we have a pair of old Boston maps, from 1803 and 1863. Boston is probably built on more man-made land than any other city in North America, so its maps tell a dramatic story of geographical transformation spurred by prosperity, pollution, technological advances, and social change. The first map is from a Boston Directory—like an 1800s Yellow Pages where you could look up your innkeeper or ropemaker—and depicts a slender peninsula between the Harbor and the Charles River; Washington Street exists already but becomes an island at high tide. Our second map is from an auction catalog selling plots of land in the newly created, or still in progress, Back Bay neighborhood (formerly a bay). One of Boston’s most desirable areas today, Back Bay was built to seclude affluent families from an increasingly crowded and impoverished downtown—essentially creating a miniature suburb in the heart of the city.
