The Big Rock

Highlight • Historical Site

Menhir part of the local history to discover.
Be careful, the place is very swampy and it is more easily accessible in dry weather 😉.

Le dolmen d’Hamel, une des rare allée couverte dans le Nord
Connu aussi sous le nom de « Pierre-aux-savates » ou « Cuisine des Sorciers », le dolmen du Bois d’Hamel, dans la vallée de la Sensée, est un des rares exemples d’allée couverte encore visible dans notre région. On le date du néolithique final, environ 2800 -2000 av. J.C.
M. Bottin, secrétaire de la société des Sciences de Lille, donna une description détaillée de l'édifice après une visite sur place en 1805. Il comporte alors quatre dalles supports en place mais deux furent renversées par des ouvriers vers 1830.
Il est classé au titre des monuments historiques le 18 avril 1914. L'édifice comporte encore deux orthostates recouverts d'une table de couverture. Cette dernière mesure 3,40 m de longueur sur 2,45 m de large et 0,35 m d'épaisseur. Selon la description de Bottin, il s'agirait d'une allée couverte d'environ 5 m de long sur 1 m à 1,30 m de large, ouvrant vers le sud. Toutes les dalles sont en grès très dur et très fin, de couleur rose clair.
La surface de la table de couverture comporte une douzaine de cavités cylindriques, d'une largeur et d'une profondeur de 7 à 8 cm, dont huit sont prolongées par des rigoles de 10 à 12 cm de longueur qui sont peut-être d'origine naturelle mais dont la régularité et le poli indiquent une intervention humaine. Selon L. Desailly leur disposition correspondrait à une représentation de la constellation de la Grande Ourse. Selon la tradition locale, les pierres n'ont pas été taillées de mains d'homme et elles servaient de cuisine à des sorciers ou de refuge à des êtres malfaisants, appelés Caramaras, et à des bohémiens nomades. L'origine du nom de Pierre Chavatte viendrait soit de chavatte ou chawatte, nom en patois local de la chouette, ou d'une déformation du mois savate, en raison des cavités et sillons visibles sur la table assimilées à des empreintes de talon. Le nom de Cuisine des Sorciers viendrait de ces mêmes cavités cylindriques qui peuvent faire penser à de petits pots

Roost-Warendin Slag Heap 138

Highlight • Natural Monument

Small heap located near the College of Roost-Warendin. It is less known than its neighbor of the Paturelles (bigger and more fun), but it deserves a trip if you are in the area. You will find lots of little singles forming a real labyrinth in the middle of birch trees (with passages sometimes very narrow). Don't hesitate to get lost ... without forgetting a very steep little climb for the more athletic!

Terril 125 of Sainte-Marie

Highlight • Natural Monument

A small part is accessible by bicycle but you will have to cross a few rocks which prevent motor vehicles from venturing there.

The menhir is located in the marsh of Aubigny-au-Bac, on a footpath leading to Brunémont. It is a block of Landenian sandstone 2.90 m high (including 1.48 m above ground) by 2.15 m wide and 0.70 m thick. It is said to have been sunk to about 2.40 m. Shaped like a horse's head, it is associated with a prehistoric megalith despite the absence of evidence.

It is a magical place, sheltered in a small clearing, which is accessed by a footbridge. Don't make (too much) noise ...

Accessible by gravel if you follow the trail. Please note that the entrance on the Bruille lez Marchiennes side has been blocked off to prevent the passage of cars. it will be necessary to climb some rocks to pass.
