“Magdalene” laundries dotted the Irish landscape since 1765. These commercial washing businesses were operated by nuns, who made “fallen women” — prostitutes, flirts, orphans, single mothers, and even the disabled — spend their days (and nights) scrubbing linens in order to “wash away their sins.” In 1993, a mass grave containing 155 corpses was unearthed on the grounds of a Madgalene laundry, leading to a media frenzy and an official state apology in 2013. The discovery also led Erin Layton to write a one-woman play set inside the Good Shepherd Magdalene Laundry in Dublin. Magdalen, which stars Layton, will be presented twice this week at the New York Irish Center as part of a jam-packed week of entertainment. An additional photos and more information follows.
