The Occupation of the Rhineland from 1 December 1918 until 30 June 1930 was a consequence of the collapse of the Imperial German Army in 1918, after which Germany's provisional government was obliged to agree to the terms of the 1918 armistice. This included accepting that the troops of the victorious powers occupied the left bank of the Rhine and four right bank "bridgeheads" with a 30-kilometre (19 mi) radius around Cologne, Koblenz, Mainz and a 10-kilometre (6 mi) radius around Kehl. Furthermore, the left bank of the Rhine and a 50-kilometre-wide (31 mi) strip east of the Rhine was declared a demilitarized zone. The Treaty of Versailles repeated these provisions, but limited the presence of the foreign troops to fifteen years after the signing of the treaty (until 1934). The purpose of the occupation was on the one hand to give France security against a renewed German attack, and on the other to serve as a guarantee for reparations obligations. After this was apparently achieved with the Young Plan, the occupation of the Rhineland was prematurely ended on 30 June 1930. The administration of occupied Rhineland was under the jurisdiction of the Inter-Allied Rhineland High Commission with its seat at the Upper Presidium of the Rhine Province in Koblenz.

The Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (Bundesamt für Ausrüstung, Informationstechnik und Nutzung der Bundeswehr; BAAINBw) is a German government agency for equipping the German armed forces (Bundeswehr) with modern weapon systems considering cost efficiency aspects. In doing so, it is responsible for developing, assessing and procuring weapon systems. It was founded in 2012 by merging the Bundesamt für Wehrtechnik und Beschaffung (BWB) and Bundesamt für Informationsmanagement und Informationstechnik (IT-AmtBw) with the goal of producing synergies. The Bundeswehr Technical and Airworthiness Center for Aircraft is a branch of the agency. The BAAINBw is located in Koblenz, Rhineland-Palatinate and directly reports to the Federal Ministry of Defence (Germany) located in Bonn and Berlin.

The Pfaffendorf Bridge (German: Pfaffendorfer Brücke) is the oldest bridge over the Rhine at Koblenz, in the German state of Rhineland-Palatinate. It carries federal highway B 49 over the Rhine, and connects central Koblenz with the suburbs of Pfaffendorf and Ehrenbreitstein. The first bridge was completed in 1864. It was destroyed in the Second World War and the current bridge was opened in 1953.

Koblenz (UK: koh-BLENTS, US: KOH-blents, German: [ˈkoːblɛnts] (listen)) is a German city on the banks of the Rhine and the Moselle, a multinational tributary. Koblenz was established as a Roman military post by Drusus around 8 B.C. Its name originates from the Latin (ad) cōnfluentēs, meaning "(at the) confluence". The actual confluence is today known as the "German Corner", a symbol of the unification of Germany that features an equestrian statue of Emperor William I. The city celebrated its 2000th anniversary in 1992. It ranks in population behind Mainz and Ludwigshafen am Rhein to be the third-largest city in Rhineland-Palatinate. Its usual-residents' population is 112,000 (as at 2015). Koblenz lies in a narrow flood plain between high hill ranges, some reaching mountainous height, and is served by an express rail and autobahn network. It is part of the populous Rhineland.

Koblenz Fortress was part of a Prussian fortress system near the city of Koblenz in Germany which consisted of the city fortifications of Koblenz and Ehrenbreitstein and exterior supporting constructions such as entrenchments and forts. Koblenz fortress was built in three stages: 1815–1830, 1859–1868 and 1871–1886. The designers were: Ernst von Aster and Gustav von Rauch. Individual parts of the fortification have been preserved, other parts were demolished over the course of time. For example, in 1890 part of the fortress was declassified, the gates were demolished between 1896–1899 and further structures were demolished in the years 1920–1927.

The Basilica of St. Castor (German: Basilika St. Kastor or Kastorkirche) is the oldest church in Koblenz in the German state of Rhineland Palatinate. It is located near Deutsches Eck at the confluence of the Rhine and the Moselle. A fountain called Kastorbrunnen ("Castor well") was built in front of the basilica during Napoleon’s invasion of Russia in 1812. Pope John Paul II raised St. Castor to a basilica minor on 30 July 1991. This church is worth seeing for the historical events that have occurred in it, its extensive Romanesque construction and its largely traditional furnishings. Since 2002, the Basilica of St. Castor has been part of the UNESCO World Heritage cultural landscape of the Upper Middle Rhine Valley. In addition, it is a cultural property protected under the Hague Convention.

The Kastorbrunnen (Saint Castor's Fountain) in the forecourt of the Basilica of St. Kastor in Koblenz, Rhineland-Palatinate, Germany, is a curious testimony of the Napoleonic Wars. The fountain, built in 1812, was connected to the first aqueduct of the Elector Palatine.

Between Bingen and Bonn, Germany, the river Rhine flows as the Middle Rhine (German: Mittelrhein, pronounced [ˈmɪtl̩ˌʁaɪn] (listen)) through the Rhine Gorge, a formation created by erosion, which happened at about the same rate as an uplift in the region, leaving the river at about its original level, and the surrounding lands raised. This gorge is quite deep, about 130 metres (430 ft) from the top of the rocks down to the average water-line. The "Middle Rhine" is one of four sections (High Rhine, Upper Rhine, Middle Rhine, Lower Rhine) of the river between Lake Constance and the North Sea. The upper half of the Middle Rhine (Rhine Gorge) from Bingen (Rhine-kilometer 526) to Koblenz (Rhine-kilometer 593) is a UNESCO World Heritage Site as a striking cultural landscape with more than 40 castles and fortresses from the Middle Ages, unique terraced vineyards, and many wine-villages. The lower half from Koblenz (Rhine-kilometer 593) to Bonn (Rhine-kilometer 655) is famous for the formerly volcanic Siebengebirge with the Drachenfels volcano. Both parts together are known as "the romantic Rhine". The Middle Rhine Valley has been a major tourist attraction since the 19th century. It is also home to some 450,000 people. The valley owes its special appearance to both its natural shape and human alterations. For two millennia, it has been one of the most important routes for cultural exchange between the Mediterranean region and northern Europe. Situated in the heart of Europe, it was sometimes a border and sometimes a bridge between different cultures. The history of the valley reflects the history of Western Europe. With its many outstanding monuments, its hills full of vines, its settlements crowded on the narrow river banks, and the rows of castles lined up on the hill tops, it is considered the epitome of the Rhine romanticism. It inspired Heinrich Heine to write his famous poem "Lorelei" and Richard Wagner to write his opera Götterdämmerung. The vineyards along the Middle Rhine form the wine-growing region of the same name, see Mittelrhein (wine region).

Deutsches Eck (German: [ˈdɔʏtʃəs ˈʔɛk], "German Corner") is the name of a promontory in Koblenz, Germany, where the Mosel river joins the Rhine. Named after a local commandry of the Teutonic Order ("Teutonischer Orden"), it became known for a monumental equestrian statue of William I, first German Emperor, erected in 1897 in appreciation of his role in the unification of Germany. One of many Emperor William monuments raised in the Prussian Rhine Province, it was destroyed in World War II and only the plinth was preserved as a memorial. Following German reunification, a replica of the statue was erected on the pedestal after controversial discussions in 1993. It is today a Koblenz monument and a popular tourist attraction.

The Old Castle (German: Alte Burg) was a former Elector-owned, substantial water castle in the German city of Koblenz, incepted in the 13th century. It is today reduced to the later Burghaus (castle house); which houses the city archives. It sits on tall foundations and has a tall, black slate roof with further floors in the attic and two small cupolas. The lowland castle abutted the remaining building in the old town quarter. The castle house stands tall, next to the Moselle's right-bank towpath downstream of the strategic Baldwin Bridge (lowest crossing of the river) built in 1342. The bridge, much-repaired, remains intact.

Koblenz-Ehrenbreitstein station is the only station on the right (eastern) bank in the city of Koblenz in the German state of Rhineland-Palatinate. It is on the East Rhine railway (German: Rechte Rheinstrecke, Right Rhine line) at the foot of the Ehrenbreitstein hill in the Ehrenbreitstein district, next to the Rhine.
