West Street Building, 1905.

Cass Gilbert, later architect of the Woolworth Building, designed this speculative office tower for developer General Howard Carroll.

Originally, 90 West Street stood across the street from the Hudson River wharves and warehouses used by its tenants. This area became landfill in the late 1960s using material excavated in the construction of the World Trade Center. It is now occupied by the World Financial Center and Battery Park City.

The tower's restrained granite base and shaft contrast sharply with its crown-like finale which is marked by a graceful three-story arcade, elaborate over-hanging cornice, and mansard roof decorated by pinnacles, look-outs, and niches – all expertly rendered in terracotta in the style of the French Renaissance. This was Gilbert's most elaborate use to date of colored glazed terracotta and can be seen as a clear precursor to the Woolworth Building.

Badly damaged on September 11, 2001, the debris from the towers falling just a few hundred feet away tore gashes into the facade. Two workers were killed in an elevator and the entire interior was completed gutted by fire. The facade of 90 West Street remained shrouded in a protective covering for years as restoration was undertaken. Unveiled a few years later, the rehabilitation of the building was honored by the National Trust for Historic Preservation in 2006.
