4. Herald Square Used To Have The World’s Biggest Hotel

The original cast-iron gate of The McAlpin Hotel

Now an apartment building called Herald Towers, the Hotel McAlpin used to be the world’s biggest hotel when it opened. It had 1,500 rooms and a basement restaurant called the Marine Grill with terra cotta ornaments and vaulted ceilings. It also had murals showing New York City’s history. These, along with a cast-iron gate from the hotel, were moved to the Fulton Street station in 2000.
