By the term shrine is understood a church or other sacred place to which numerous members of the faithful make pilgrimage for a special reason of piety, with the approval of the local ordinary. – Canon 1230
At Shrines the means of salvation are to be supplied more abundantly to the faithful by diligent proclamation of the word of God, the suitable promotion of liturgical life especially through the celebration of the Eucharist and of penance, and the cultivation of approved forms of popular piety. – Canon 1234
