Built in 1863, the building is an example of an âold-lawâ tenement (as defined by the Tenement House Act of 1867) and was home over the years for some 7,000 working class immigrants. Though the basement and the first floor have been renovated, the rest of the building looks much the same as it did in the 19th century, and has been designated a National Historic Site.
