Monument and History


Coblenz belongs to the oldest cities in Germany. Already 800.000 years ago, Stone Age men resided there. After todays' knowledge, the location was colonized from around 9.000 before Christ and around 1.000 before Christ developed to an important craft and trading center by the Celts.

The Ehrenbreitstein was colonized from around 3.500 before Christ and already 1.000 before Christ developed to a fortified noble’s residence with ramparts and trenches. The rock was a good location to control the Moselle mouth, the river crossings and the mineral deposits in the backcountry.

When the Romans came to the Rhine, they built their Castellum apud Confluentes (“fort at the confluence”) around 27 before Christ and a bridge over Rhine and Moselle. Moreover, they built the fort Niederberg on the right side of the Rhine to protect the Germania Superior Limes. Under emperor Konstantin the late antiquity fort Confluentes was built from 306 to 337 after Christ, a 5.8 ha large fortification on the area of todays’ old city. Its walls protected the city for more than 100 years and was only stripped down in the 19th century.

Then came the 800 years of Trier bishops and electors. They bought the castle Ehrenbreitstein built in 1000 in 1020, one of the most secured castles of its time and kept the sanctuaries of the country there. The fort was further developed to fortress Ehrenbreitstein along with the improvement of war methods in the early 16th century.

Only after the Thirty Years War, which was very painful for the city, Coblenz received a bastion like fortification ring. Changing occupants and owner, among them the French, changed the functions and the look of the fortifications of Coblenz and Ehrenbreitstein constantly until the 19th century. Finally after the Congress of Vienna in 1815, the Rhenish possessions of the Trier electoral state were transferred to the kingdom Prussia, who made Coblenz the capitol of the Rhine province and also gave the order to develop the Prussian large fortification.

One of the most important fortifications of Europe was developed and mentioned in the same breath with the fortresses in Gibraltar and Paris. Coblenz got a key location as bulwark against France between the large fortifications Cologne and the state fortification Mainz.

In 1886 after the German-French War, the fortress was classified as less important. With enactment of 1890 the slighting of the west Rhenish fortifications started, which mostly regarded the Coblenz city fortification. The east Rhenish fortifications stayed operational until World War I and were reinforced by concrete dugouts.

On 25th August 1924, law closed down the whole fortification Coblenz and Ehrenbreitstein. Further defortification before and after changed the cityscape. Fortress Ehrenbreitstein was spared from this and classified as dominating the landscape and of historic meaning by the inter-allied military control commission in 1922.
