Gently curving South William Street is another remnant of the old Dutch street plan. The quiet handful of low-rise buildings we see hark back to Manhattan's seafaring days. Again, note the contrast with the surrounding skyscrapers.

At numbers 13 and 15, the two neo-Flemish buildings demonstrate that even a century back Manhattan landlords altered their holdings to maximize rental income. Amos Eno, merchant, realtor, and major collector of views of early New York, was no exception. In 1903 he hired C.P.H. Gilbert to recast his two mid-19th century Greek Revival warehouses into a more fashionable, or at least different, guise.

At number 19 on the upper floor you can glimpse the "before" appearance of another face-lifted neighbor.

Finally, at number 21 is Block Hall, a Tudor-like half-timbered conglomeration built as a private club house. Most recently it operated as the Italian Alps restaurant. It awaits a new calling.
