Mont St. Jean

Mont St. Jean is a hill, castle, and religious site in the commune of Dudelange, in southern Luxembourg. The summit is at 417 metres .

Mont St. Jean has probably been a point of religious interest since pre-Christian times. The annual pilgrimage to St. John's Chapel, on the summit, on St. John's Eve was accompanied in the Middle Ages by ecstatic dancing. The ritualistic dance, a surviving example of which is found at Echternach, was supposedly performed to ward off St. Vitus Dance, but is possibly a relic of pagan times.
