In 1998, ten vacant niches above the west entrance to Westminster Abbey were filled with representative 20th century Christian martyrs. Among them, shown here in the center, is U.S. civil rights leader Martin Luther King, Jr. He is flanked in this photo on the left by Princess Elisabeth of Hesse and by Rhine, who married into the Romanov household and would be the last Russian empress. She left the household to become a nun and was buried alive during the Bolshevik revolution. To the right of King's statute is Oscar Romero, the fourth Archbishop of San Salvador, who was assassinated in March 1980 after calling on Salvadoran soldiers to desist in carrying out the government's orders to repress the Salvadoran people.
