On the southwestern tip of Manhattan, the maze of stone and steel suddenly gives way to an expanse of greenery, Battery Park. Here, strolling along the newly revamped waterfront esplanade, visitors can enjoy upclose views of the Statue of Liberty and the harbor islands, and catch ferries to get even closer. The esplanade features a number of memorials and sculptures including the 22-ton Sphere by Fritz Koenig, salvaged from the World Trade Center Plaza.
