Michel Raulier: The Nail Tree of Stambruges Tree worship in our region is very ancient. Proof of this is the discovery in Blicquy, in the place called "Ville d'Anderlecht," of a set of 120 posts up to 90 cm in diameter. These may have served as supports for offerings, as evidenced by the numerous iron pins found in the filling holes. This could correspond to an artificial sacred grove housing deities, similar to Lucan's description of petrified forests in Pharsalia. In the past, trees, with their longevity and majestic shape, aroused a sense of sacredness in the minds of our ancestors. They were also believed to be capable of helping people solve their problems, particularly health problems. Many customs exist: walking around the tree, driving nails to fix the ailment, and tying cloths or fabrics to bind it. These trees were often Christianized by the installation of religious images or a chapel nearby. One example among others is that of Notre Dame de Foy. In Foy, near Dinant, a woodcutter discovered a 15th-century statuette in the heart of a very ancient oak tree in 1609. Long forgotten, the figurine bearing the image of the Virgin had been placed in a niche carved into the trunk. Over time, the wood completely covered it and erased its memory. In Stambruges, there is one of these remarkable trees, and beside it is a chapel, called "the chapel of Erconpuch" or, by another name, "the chapel of Arc-au-Puche," dedicated to the Virgin Our Lady of Arc-au-Puits, formerly called the Virgin of the Woods.

In the forest of Stambruges is 'la Fontaine bouillante', the bubbling spring where, according to legend, a mistress of the Prince De Ligne drowned with her coach and the crew of the coach tries to surface. In reality, it is spring water bubbling up through a crack in the earth. https://nl.wikipedia.org/wiki/Bos_van_Stambruges
