165 Halsey Street

165 Halsey Street, formerly known as the Bamberger Building, is a 14-story, office tower in Downtown Newark, New Jersey. Built in 1912–1929, it was designed by Jarvis Hunt. The building spans the entire block between Halsey Street, Market Street, Washington Street, and Bank Street. 165 Halsey Street is a major colocation center in New York metropolitan area; according to Center for Land Use Interpretation, it is among the world's largest carrier hotels. It is a contributing property to the Four Corners Historic District.

Bamberger's
165 Halsey Street was initially built in 1912 as an eight-story, 500,000 sqft flagship store of Bamberger's to expand the operations from its original store across Halsey Street. It was expanded twice in 1922 and 1929 to become a 14-story building with a total floor area of 1.2 e6sqft. The building address was 109-135 Market Street. After Bamberger's expanded its operations to suburban stores, some parts of the building were converted to an office space and the building became the headquarters of Bamberger's. After R. H. Macy & Co. took over Bamberger's, the operations in New Jersey stores retained the Bamberger's name. As the sales continued to decline at the Newark location and Macy's New York and New Jersey merged their operations, the building lost the headquarters status and the store itself was renamed Macy's. In 1992, Macy's closed the Newark store and the building remained vacant until 1996.

Colocation center
After the closure in 1992, the building stayed vacant until October 1996. Samuel Jemal saw a potential of retrofitting the building into a major telecommunication center. The building was built with sturdy construction and its large areas are suitable for large equipment of telecommunication switches and data center operations. The building became known as 165 Halsey Street after the conversion. Early tenants included Level 3 Communications, and MCI Communications which took up a large amount of space within 18 months of the reopening. By 2004, many other telecommunication companies including Verizon Communications and Qwest had moved in.
