770 Eastern Parkway (Yiddish: 770 איסטערן פארקוויי), also known as "770", is the street address of the World Headquarters of the Chabad-Lubavitch Hasidic movement, located on Eastern Parkway in the Crown Heights section of Brooklyn, New York, in the United States.
It took months, perhaps years for a small crew of Lubavitchers to dig a secret passageway underneath the famed headquarters of the Chabad movement. They would not let it be filled so easily.
According to Haredi news source Collive.com, the students who tried to stop the filling of the tunnel were mostly from Israel and associated with Chabad Messianism — whose adherents believe that Schneerson, the sixth Lubavitcher Rebbe, was the Messiah. The Chabad-Lubavitch movement publicly disavows those beliefs.
