3. Milligan Place
Milligan Place, tightly squeezed between two buildings on 6th Avenue near 10th Street, is home to one of New York City’s quaintest courtyards. It also has an equally whimsical cast-iron doorway featuring “Milligan Place” in fancy script. Originally built as working class boarding houses for Basque waiters, the 1850s homes enclosing it were home to renowned playwright Eugene O’Neill and George Cram Cook, founder of the Provincetown Players.
