2. There’s a Secret Staircase Inside the American Irish Historical Society

991 Fifth Avenue was built in 1900 as the private home of Mary A. King, daughter of John A. King, a politician who served as governor of New York in the 1850s. The design of the building adhered to the British and European standard that servants should have a completely separate means of access within the building. As such, a separate staircase spirals through the townhouse at 991 Fifth Avenue, landing in the kitchen galley on the second, main floor of the home. A month ago before the New York City primary, Bill Clinton gave a campaign speech for his wife Hillary at the American Irish Historical Society, and was taken through this secret staircase.
