In the 1980's, when the west towers of the National Cathedral were being built, a competition was held to design modern gargoyles to feature on the towers. One of the winners was this - a gargoyle featuring the Star Wars villain 'Darth Vader'. I did not see the original sculpture - this was a replica available to purchase (and ship,worldwide), in the Cathedral gift shop.
In the 'Human Rights' porch of the Cathedral were a number of modern sculptures of 20th century figures renowned for their contributions to human rights. One was this statue of Eleanor Roosevelt.
Another, dedicated as recently as 2012, was this sculpture of the face of Mother Teresa of Calcutta.
