Ireland is a country with a long pilgrimage tradition. The tour can start in Glendalough which is an ancient monastic city. It continues to Baltinglass where the ruins of Cistercian Abbey were found. Furthermore, it’s worth to head to the Rock of Cashel which is a medieval building complex which performed both functions: sacred and defensive. However, the religious place with really fascinating history is Knock Shrine. The Apparition took place there in 1879 and thanks to Knock Museum, visitors are invited to step back in time to this date.
