The buildings date from 1908–1929 and the site was added to the National Register of Historic Places on August 22, 2012.

John A. Roebling, the designer of the Brooklyn Bridge, founded his steel wire manufacturing company on the site in 1849.

Block 3 suffered a number of fires in the 1910s, some attributed to arson due to worker unrest.

It is also quite close to the Trenton Transit Center on the Northeast Corridor, the terminus of the River Line, providing easy rail access to New York City and Philadelphia.

Nearby landmarks include the Italian Peoples Bakery and the New Jersey State Prison.
