Pastorsgrät Gorge

Highlight • Gorge

Pastorsgrät

Ein tragisches Ereignis mit tödlichem Ende, dessen tatsächlichen Hintergründe und wahren Ursachen vom Volksmund gem in das Dunkel des Geheimnisvollen und Unaufgeklärten gedichtet werden, soll an dieser Stelle erzählt werden. Zunächst zum Ort des Geschehens: Der Gisinger Wald ist gekennzeichnet durch zahlreiche tief eingeschnittene Kerbtäler, die sogenannten „Gräten“. Abzuleiten ist das Wort vom mittelhochdeutschen „graht“, was „Graben“ oder „Schlucht“ bedeutet. Die imposanteste Grät ist die Pastorsgrät. Dieser durch die Erosion des Wassers über Jahrtausende geschaffene tiefe Einschnitt schließt den obersten Teil des Mittleren Buntsandsteins auf und zeigt ein fast vollständiges Profil des oberen Buntsandsteins. Deutlich sind der lithologische Aufbau und die typischen Sedimentationsprozesse zu erkennen. Der Name „Pastorsgrät“ erinnert an ein tragisches Unglück, welches sich hier im Jahre 1857 ereignet hat. Damals stürzte der Pastor von Itzbach, Hubert Hoffmann, auf dem Nachhauseweg bei Dunkelheit in die tiefe Schlucht und erlitt tödliche Verletzungen. Was war geschehen? Am frühen Morgen des 20. September 1857 begab sich Pastor Hoffmann auf Einladung seines Beruser Amtskollegen zu Fuß durch das Itzbacher (Gisinger) Loch auf den Weg zur Oranna-Kirmes. Dort in Berus übernachtete er nach der Kirchweih-Feier im Pfarrhaus, um am folgenden Tag in der Frühe auf den Nachhauseweg aufzubrechen. Eine Zwischenstation legte er im Bedersdorfer Pfarrhaus ein. Es war schon dunkel, wohl gegen 8.00 Uhr abends, als Pastor Hoffmann den stockfinsteren Wald zwischen Gisingen und Itzbach erreichte. Doch an diesem Abend traf er nicht ein in seinem Pfarrhaus. Erst am Morgen des nächsten Tages fand ihn eine Suchmannschaft auf einem Felsen liegend am Grunde dieser etwa 10m tiefen Grät; „mit eingedrücktem Hirnschädel“, wie die Beruser Chronik berichtet. Dieses schreckliche Ereignis dürfte auf einen Unfall zurückzuführen sein, da Pastor Hoffmann in finsterer Nacht wohl den Weg verfehlte und todbringend in die Schlucht hinab stürzte.

Lourdes grotto

The grotto, built by Matthias Staudt and Matthias Diederich, (1906) after your return from a Lourdes pilgrimage, they recreated the pilgrimage church in Lourdes, which you clearly succeeded in doing. A plaque in front of the Lourdes grotto gives the year 1912 as the construction date. Http://greimerath-hochwald.de/tourismus/sehenswuerdheiten

Niederlimberg Rock Caves

Highlight • Cave

The Niederlimberg rock caves are located at the entrance to Wallerfangen, when you come from Dillingen on the right-hand side. The chain link fence has a few holes so you can get back in there. Unfortunately, I was wearing shorts and because of the nettles I didn't go in but only took a few photos from the outside.

"Here lived the poorest of the poor who could not pay the rents for better apartments.
The Wallerfangen Poor Association (founded in 1838) supported the residents of these rock houses very early on. From 1846 he provided regular emergency supplies. "

Recently a lot of green was removed so that you can see even more entrances to caves. There are a few holes in the chain link fence so that you can also get in. However, inside the entrances to the "hall" or possibly other rooms are unfortunately bricked up. I guess because of the risk of collapse, because there have been landslides in this area.

A beautiful place of worship, the grotto surmounted by a cross and in the center a statue of Our Lady, on the pedestal the inscription "Ave Maria". With these words “Ave Maria, gratia plena” (“Hail Mary, full of grace”) the angel's greeting to Our Lady begins as he brings the heavenly message to Mary, who lives in Nazareth and who is betrothed to Joseph, that she is Jesus To bring Christ, the Son of God, into the world. The text has become a widespread prayer that the faithful address to Our Lady to invoke her intercession or to express her gratitude. Some votive tablets testify to this.

The Marian pilgrimage site of Lourdes is located in the French Pyrenees and is visited by a large number of people every year, including many sick people who are hoping for a cure. The devotional image of Our Lady has become widespread - not only in France - everywhere, as here in Greimerath, believers have built Lourdes grottos. The ecclesiastical commemoration day "Our Lady in Lourdes" is on February 11th, this is the anniversary of the apparition of Mary (1858), when Our Lady appeared to 14-year-old Bernadette Soubirous in a rock grotto not far from Lourdes. Bernadette later became a nun and died at the age of only 35. On December 8th (the feast of the Immaculate Conception of Mary) in 1933, she was canonized by Pope Pius XI. The day of remembrance of the Lourdes Madonna is also World Day of the Sick.
