Brittany Hall, NYU

Formerly the Brittany Hotel, Birttany Hall was built in 1929 and has housed private residents at several points in its history, including Al Pacino and journalist Walter Winchell. During Prohibition its penthouse was used as a speakeasy which students say still hosts phantom parties to this day. Witnesses have described music and disembodied footsteps coming from the upper levels of the building, and some say they feel as though they are being watched.
