Amenities for residents of Tiber Island include
the Thomas Law House, an historical landmark on the National
Register. Built in 1784, this handsome Federalist mansion
at the corner of our grounds at Sixth and N Streets, has
been the home and social center for some of America’s
leading figures including Thomas Law and his wife, Eliza
Parke Custis, the spirited eldest granddaughter of the
First Lady, Martha Washington.
