かつてのSchlammefeld鉄鉱石鉱山にあるGiele Botter自然保護区は、ハイキングに非常に美しい場所です。最も深い部分は湿っていることが多いですが、2026年の長く暑い夏の後の秋には完全に乾いていました。岩石は、鉄の錆（酸化）によってオレンジ色に染まっています。採掘場は現在主にシラカバで覆われていますが、今後数年間でさらに生物多様性が高まっていくことでしょう。

The most beautiful part of the walk. No difficulties despite the route being marked in red on the map.

Great place, nice and cool

The Trench of Gates: Gateway to Gaume, Gateway to Legends 1. What is it? Physical Description The Trench of Gates is a deep and spectacular rocky gorge, naturally carved by the Vire River (a tributary of the Semois) into the sandstone plateau of the Gaume forest. Located in the village of Dampicourt (commune of Rouvroy), on the French border, it forms a narrow and winding notch, framed by high sandstone walls and strangely shaped rocks. Its name comes from its topography: the site gives the impression of crossing several successive natural "gates." 2. A Strategic Position: Military History The true fame of the Trench of Gates comes from its historical role as a natural fortress and strategic border post. A Gallic Stronghold? : Its easily defensible configuration suggests that it was used as a refuge since the Gallic era. The Roman Fort: Its strategic role became evident during the Roman era. The Romans established a castellum (a fortified camp) there to control the passage between Belgic Gaul and Imperial Trier, and to protect the nearby Roman road. Remains of these fortifications were still visible several centuries ago. A Millennial Challenge: Due to its position on the border, the site has been contested and fortified throughout history, from the Middle Ages to modern wars. It offered an ideal control point over one of the few passable passages through the region's wooded terrain.

Beautiful natural area.

The Tranchée des Portes covers an area of 100 hectares. It is the largest Iron Age stronghold in Belgium. This development required an abundant workforce. The construction and maintenance of the rampart suggest a well-organized social entity. Unlike Montauban, which was occupied occasionally, the Tranchée des Portes is not a refuge but an oppidum, that is to say, a fortified site where people settled for the long term with their livestock and crops. It is a fortification that owes its name to the deep ditch (5 m) that precedes its rampart. Consisting of an earthwork over 3 m high, formerly surmounted by a palisade, this barrier, pierced by 3 gates, extends over 1 km. This type of defensive site is called a barred spur. It was often used in the protohistoric period (Iron Age). We chose a place with 2 or 3 steep and almost impassable sides and we blocked access by building a wall on the vulnerable side with what we found on the site (stones, trees, earth)
