The team unearthed the foundations of medieval defensive buildings of the fourteenth and XVesiècles, including a tower retained by 1.50 m high, a square building surrounded by ditches 8 m deep, and a monumental pillar supporting a bridge -levis. These findings will help to establish a clear plan of the medieval castle. Balls hard stone and cast iron, and lead ammunition, testify to the military history of this strategic stronghold, next three borders, highly coveted by the Kingdom of France in the sixteenth century. 

The scale of the excavated remains was unexpected, the castle has undergone fires, partial demolition and subsequent seats. Under more than thousand five hundred tons of fill, archaeologists have found witnesses to the history of the castle back as the twelfth century. The researchers collected a wide variety of objects from the Middle Ages and the Renaissance glassware, ceramic tableware (Rhineland stoneware and glazed pottery Moselle), tile stoves decorated, tools, weapons, coins, etc. They reflect a rich economy in a German aristocratic background booming during these periods.

The original core of the Middle Ages to the Renaissance castle 

This second excavation campaign that has just begun is already rich in remains. Researchers have identified in the heart of the castle, an original building of the thirteenth and fourteenth centuries. They now have a full view of the building, half of which was excavated in 2013 from 8 m wide and at least 15 m long, this original core consists of four parts: a large central room, a smaller one kitchen with an impressive bread oven, and a room where the murals were found. The width of its foundation to suppose that included a floor. Right next to this building, archaeologists off a paved about 50 m2 courtyard dating from the sixteenth century. This is the entrance courtyard of the castle built in the Renaissance, which was then leveled in the nineteenth century. In the courtyard, a water tank six feet deep is a management system of water probably prior to the Renaissance as should the study confirm the carbon 14 with a layer of fill on fire. 

Military entanglements in the sixteenth and seventeenth centuries

The search of the barracks of the seventeenth century, which begins only is already dense in information. The barracks built in the 1680s by Louis XIV aims to store troops near the Luxembourg invade it in 1684. 

Archaeologists are now generating the front of this imposing building 40 m long which had three levels. The excavation of this building is a source of surprises. Indeed, the previous state is best known for having been leveled, or archaeologists emerged today as the barracks of the oldest buildings, dating from the fifteenth and sixteenth centuries. A deposit of ten coins dated 1550-1560, including one in the likeness of Charles V, was found. This scholarship soldier, lost or deliberately hidden, confirms the passage of troops of the powerful German emperor in Rodemack. Indeed, at that time, both superpowers vie for Europe: the kingdom of France and the Holy Roman Empire. Charles V and his troops through the city of Luxembourg and Rodemack, went to Metz in 1552 they besiege for more than two months. The current excavation of the buildings of the fifteenth and sixteenth centuries, found in the barracks should reveal new aspects of the history of conflict and allow the reconstruction of the successive planes of evolution of the castle.
