1. The Mall, May 2007. When Frederick Law Olmsted and Calvert Vaux began work on Central Park in the 1860s, the vast area at their disposal was little more than marshland. Their vision was simple: To build the world’s greatest park, a place that could be enjoyed by all New Yorkers, regardless of colour, class or creed. In these respects, and indeed so many others, The Big Apple’s premier green space has been a resounding success. For those seeking a simple walking route through the middle of the park, look no further than The Mall, a pretty tree-lined walkway running from 66th to 72nd street.
