Come join us at Dublin Castle as Dublin Archbishop Diarmuid Martin and University President Rev. John Jenkins, C.S.C., celebrate Mass in Ireland on game day morning at 9:00 a.m. Originally built in the 13th century on a site previously settled by the Vikings, Dublin Castle functioned as a military fortress, a prison, treasury, courts of law and the seat of English Administration in Ireland for 700 years. Dublin Castle is now used for important State receptions and Presidential Inaugurations. The Mass at Dublin Castle will be free and open to the Notre Dame extended family. Please note: Mass will be held outdoors with standing room only for the general public.
