New York City's Knickerbocker Hotel reopens more than a century after its debut
For history buffs, there is one part of the Knickerbocker that unfortunately will not be re-opening: The sub-level ballroom, with a direct entrance from the subway platform.
When the hotel was built, the nascent subway was so exciting to John Jacob Astor IV he had a door — still visible today — installed to provide direct access to one of the early lines.
The area behind the door — a corridor leading to the upper levels of the hotel — is owned by the MTA, which apparently isn't interested in how much 21st century New Yorkers would be interested in a restored subway entrance.
