Oliver Plunkett was an Irish Catholic archbishop who served as the Primate of All Ireland during the late 17th century. Born in Loughcrew around 1625, he studied in Rome and served as a theology professor before being appointed to his primatial see. He is remembered for his dedicated ministry to his flock and for being the final victim of the Popish Plot, a period of intense anti-Catholic sentiment. Following his execution in London in 1681, he was eventually canonized as a saint.
