The abbey's most famous resident was the monk and author Thomas Merton. Since May 3, 1949, the abbey church has been designated a minor basilica. Today, the term "basilica" is a special designation given by the Pope to certain churches because of their antiquity, dignity, historical importance, or significance as a place of worship.
The abbey, with its large guesthouse and reputation for virtually limitless hospitality, has become a popular site for retreatants, Catholic or otherwise.
