St. Patrick’s Cathedral is the largest Gothic-style Catholic cathedral in the United States, the seat of the Archbishop of New York, and an active parish. Its construction began in 1858 but was suspended during the Civil War. Construction resumed in 1872 and the church was dedicated in 1879.
This white marble New York City landmark is located on East Fifth Avenue between 50th and 51st
Streets in mid-town Manhattan. More than 5.5 million people visit each year to see its architecture,
altars, stained glass windows, and sculptures.
It houses a replica of Michelangelo’s Pieta that is three times the size of the one in Rome. Many notable Masses have been celebrated in the Cathedral, including Funeral Masses for presidential candidate and U.S. Senator Robert F. Kennedy and baseball greats Babe Ruth and Joe DiMaggio.
The Cathedral’s stained glass windows were made in France, England and America. The great
Rose Window was a major work by the famous American stained glass artist Charles Connick.
