The Central Park Lake is a 20-acre man-made lake incorporating an existing water body but enlarged for Olmsted and Vaux’s design. In the winter of 1858, after only six months of work on Central Park, the Lake had its first season of ice-skating. The still photo above is from a 1900 movie. While skating is now prohibited on the Lake, there are two formal skating rinks in the Park. Rowboats can also be rented at the boathouse.
In 1862, Walt Whitman, resident of Brooklyn Heights wrote the following:
“Why then should not Brooklyn, in the experience of persons now living, become a city of a great million inhabitants? We have no doubt it will. We can not go over the list and description of our public institutions in this paper, although we intend to do so one of these days. We have not, in a modern city like Brooklyn, such marked specimens of magnificent architecture as the ancient or mediaeval cities presented, and many of whose ruins yet remain. For our architectural greatness consists in the hundreds and thousands of superb private dwellings, for the comfort and luxury of the great body of middle class people–a kind of architecture unknown until comparatively late times, and no where known to such an extent as in Brooklyn, and the other first class cities of the New World.”
Whitman was correct about the “great million inhabitants” that Brooklyn would achieve and the “greatness” of the architecture. See the houses he is referring to on the Brooklyn Revolution (aka Best of Brooklyn Tour)
