Exchange Place is a district of Downtown Jersey City, New Jersey that is sometimes referred to as Wall Street West due to the concentration of financial companies that have offices there. The namesake is a square, about 200 feet long, at the foot of Montgomery Street at the Hudson River. This square was created by landfilling the shore at Paulus Hook, and has been a major transportation hub since the colonial era. Vicinity A high concentration of highrise office and residential buildings in the city are located in the district radiating from Exchange Place, which since the 1990s has overtaken Journal Square as Hudson County's major business district and become a major business center along the redeveloped waterfronts in the Port of New York and New Jersey. The Mack-Cali building is host to several nesting sites for peregrine falcons. The New Jersey Department of Environmental Protection, Division of Fish & Wildlife, maintains a Jersey City Peregrine Cam at some of the sites on the building.

To the south are New York Waterway's Paulus Hook Ferry Terminal, and the two tallest buildings in New Jersey; the Goldman Sachs Tower and 99 Hudson. The Colgate Clock, promoted by Colgate-Palmolive as the largest in the world, faces Battery Park in lower Manhattan. The clock, which is in diameter with a minute hand weighing 2,200 pounds, was erected in 1924 to replace a smaller one that was relocated to a plant in Jeffersonville, Indiana. The riverfront promenade, which provides vistas of Lower Manhattan, continues along the Morris Canal Little Basin, part of Liberty State Park. To the north is the former warehouse now housing Harborside Financial Center. History As early as July 1764 a ferry began operating from Paulus Hook to Mesier's
