In the late 19th and early 20th centuries, the corporate culture of New York was a primary center for the construction of early skyscrapers, and was rivaled only by Chicago on the American continent. There were also residential sections, such as the Bowling Green section between Broadway and the Hudson River, and between Vesey Street and the Battery. The Bowling Green area was described as "Wall Street's back yard" with poor people, high infant mortality rates, and the "worst housing conditions in the city". As a result of the construction, looking at New York City from the east, one can see two distinct clumps of tall buildings—the Financial District on the left, and the taller Midtown neighborhood on the right. The geology of Manhattan is well-suited for tall buildings, with a solid mass of bedrock underneath Manhattan providing a firm foundation for tall buildings. Skyscrapers are expensive to build, but the scarcity of land in the Financial District made it suitable for the construction of skyscrapers.
