The neo-Georgian town house at center has been the official residence of the U.N. secretary general since 1972. (There's a police security booth located just out of frame to the right.) The building owes its current appearance to Anne Morgan, the youngest child of J.P. Morgan, who bought two neighboring houses here in 1921 and had them rebuilt into the structure you see above. Ms. Morgan was part of "an exodus of society from Fifth Avenue and elsewhere to [Sutton Place]", which transformed this little two-block stretch into "one of the fanciest addresses in New York".
