La Roche-en-Ardenne Castle ruins lie on a rocky outcrop dominating the green valley which is nestled in a loop formed by the river Ourthe and the steep sides of the Deistermountain. The ruins, dating back to the 11th century, look gloomy but impressive, emphasized by the roughly piled slate walls.
From the 12th century on the castle took a strategic place in the development and defence of trade and it got to be a halting place in the trading route of English wool to Lombardia in present Italy.
The castle was conquered by the French in 1681 who rebuilt the castle so that it could withstand the new artillery.
La Roche-en-Ardenne Castle was inhabited until 1780 when it was abandoned. It quickly fell to ruin when in the 19th century it was stripped of all useful materials by the villagers of La Roche.
In 1903 during superficial excavations, inside the castle walls, pieces of polished flint, a whetstone and several shards of prehistoric pottery were discovered. Also, in 1954 a Roman coin minted in the 4th century was found. In 1995 more serious excavation works started. Proof was found that the castle site once housed a Celtic oppidum and a Roman fort.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
