Basilica of St. Castor

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 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 Moselle ( moh-ZEL, French: [mɔzɛl] (listen); German: Mosel [ˈmoːzl̩] (listen); Luxembourgish: Musel Luxembourgish pronunciation: [ˈmuzəl]) is a river that rises in the Vosges mountains and flows through north-eastern France and Luxembourg to western Germany. It is a left bank tributary of the Rhine, which it joins at Koblenz. A small part of Belgium is in its basin as it includes the Sauer and the Our. Its lower course "twists and turns its way between Trier and Koblenz along one of Germany's most beautiful river valleys." In this section the land to the north is the Eifel which stretches into Belgium; to the south lies the Hunsrück. The river flows through a region that was cultivated by the Romans. Today, its hillsides are covered by terraced vineyards where "some of the best Rieslings grow". Many castle ruins sit on the hilltops above wine villages and towns along the slopes. Traben-Trarbach with its art nouveau architecture and Bernkastel-Kues with its traditional market square are two of the many tourist attractions on the Moselle river.

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.

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.

Koblenz was one of the - at last - three Regierungsbezirke of Rhineland-Palatinate, Germany, located in the north-east of the state. The region was created in 1815 as part of the Prussian Rhineland, becoming part of the new state of Rhineland-Palatinate in 1946. In 1968 the neighbouring Montabaur Region was dissolved and its territory annexed to Koblenz Region. Since 2000, the employees and assets of the Bezirksregierungen form the Aufsichts- und Dienstleistungsdirektion Trier (Supervisory and Service Directorate Trier) and the Struktur- und Genehmigungsdirektionen (Structural and Approval Directorates) Nord in Koblenz and Süd in Neustadt (Weinstraße). These administrations execute their authority over the whole state, i. e. the ADD Trier oversees all schools.

The Rhine Province (German: Rheinprovinz), also known as Rhenish Prussia (Rheinpreußen) or synonymous with the Rhineland (Rheinland), was the westernmost province of the Kingdom of Prussia and the Free State of Prussia, within the German Reich, from 1822 to 1946. It was created from the provinces of the Lower Rhine and Jülich-Cleves-Berg. Its capital was Koblenz and in 1939 it had 8 million inhabitants. The Province of Hohenzollern was militarily associated with the Oberpräsident of the Rhine Province. The Rhine Province was bounded on the north by the Netherlands, on the east by the Prussian provinces of Westphalia and Hesse-Nassau, and the grand duchy of Hesse-Darmstadt, on the southeast by the Palatinate (a district of the Kingdom of Bavaria), on the south and southwest by Lorraine, and on the west by Luxembourg, Belgium and the Netherlands. The small exclave district of Wetzlar, wedged between the grand duchy states Hesse-Nassau and Hesse-Darmstadt was also part of the Rhine Province. The principality of Birkenfeld, on the other hand, was an enclave of the Grand Duchy of Oldenburg, a separate state of the German Empire. In 1911, the extent of the province was 10,423 km2 (4,024 sq mi); its extreme length, from north to south, was nearly 200 km (120 mi), and its greatest breadth was just under 90 km (56 mi). It included about 200 km (120 mi) of the course of the Rhine, which formed the eastern border of the province from Bingen to Koblenz, and then flows in a north-northwesterly direction inside the province, approximately following its eastern border. It is now part of North Rhine-Westphalia, Rhineland-Palatinate, Saarland, and Hesse.

The Grand Duchy of the Lower Rhine (German: Großherzogtum Niederrhein), or simply known as the Lower Rhine Province (Provinz Niederrhein), was a province of the Kingdom of Prussia and existed from 1815 to 1822.

Venues include the Theater am Deinhardplatz, rehearsal stages 2 and 4 as well as the Festung Ehrenbreitstein for the summer performances. In addition, the theatre participated in the Koblenz Fortress Plays for several years. In the 2009/2010 season, it was renamed from Theater der Stadt Koblenz to its current name. Since 1970, the Clemensbrunnen has stood on Deinhardplatz in front of the theatre.

The Electoral Palace (German: Kurfürstliches Schloss) in Koblenz, was the residence of the last Archbishop and Elector of Trier, Clemens Wenceslaus of Saxony, who commissioned the building in the late 18th century. In the mid-19th century, the Prussian Crown Prince (later Emperor Wilhelm I) had his official residence there during his years as military governor of the Rhine Province and the Province of Westphalia. It now houses various offices of the federal government. The Electoral Palace is one of the most important examples of the early French neoclassical great house in Southwestern Germany, and with Schloss Wilhelmshöhe in Kassel, the Prince Bishop's Palace in Münster and Ludwigsburg Palace, one of the last palaces built in Germany before the French Revolution. Since 2002, it has been part of the Rhine Gorge UNESCO World Heritage Site, and it is also a protected cultural property under the Hague Convention.
