The Lourdes Grotto was built in 1903 on the initiative of Father Hesseler, the parish priest of Rohren. It is an expression of the deep piety and trust in God of the people. Even today, the grotto is a destination for pilgrims who implore the Virgin Mary for help in times of need.

The Olberg Grotto was built by Pastor Hesseler in 1904. The plans were drawn up by Father Rademanns of Steyl. Wagoners from Widdau and Rohren brought approximately 80 loads of rubble and approximately 30 loads of sand from the Rur. The grotto was built by the local community using manual labor, thus saving the elderly and infirm from Widdau the strenuous walk to the church in Rohren. Source: Display board.

This grotto contains an interesting little shrine: the Widdau Mount of Olives Grotto. According to the New Testament accounts of the Passion of Jesus, the Mount of Olives in Jerusalem was the scene of two events: Jesus' prayer to God the Father, during which the overtired disciples fell asleep; and Jesus' arrest.
