8. Jefferson Market Library – Most Exclusive

Jefferson Market Library

The Jefferson Market Library has one of the most unique NYC observation decks. This New York City landmark was designed by noted architects Frederick Clark Withers and Calvert Vaux (who also assisted in the design of Central Park). Its original purpose was to serve as a courthouse with an adjoining prison and market. Since 1967, it has been the home of the New York Public Library Jefferson Market Library branch.

The library’s observation deck encircles its iconic clocktower. After a climb up 149 steps, guests are treated to a special view of Greenwich Village and beyond. Untapped New York Insiders have had the pleasure of making the climb multiple times! When the library’s giant spider used as a Halloween decoration isn’t in use, it’s stored up there. The observation deck has yet to reopen after the library’s extensive renovation, but we anxiously await the day when it is!
