Bad Neuenahr-Ahrweiler (German pronunciation: [baːt ˌnɔʏənʔaːɐ̯ˈʔaːɐ̯vaɪlɐ]) is a spa town in the German Bundesland of Rhineland-Palatinate that serves as the capital of the Ahrweiler district. The A61 motorway connects the town with cities like Cologne and Mainz. Formed by the merging of the towns (now districts) of Bad Neuenahr and Ahrweiler in 1969, Bad Neuenahr-Ahrweiler consists of 11 such districts.

The Wingsbach is a small right tributary of the Ahr river. It has a length of 4.5 km and a drainage area of 5.4 km2. Colloquially it is also referred to as Maibach and in its upper course is also named Talbach.

Ahrweiler (German: [ˈaːɐ̯ˌvaɪlɐ]) is a district in the north of Rhineland-Palatinate, Germany. It is bounded by (from the north and clockwise) the districts of Euskirchen, Rhein-Sieg and the city of Bonn in the state of North Rhine-Westphalia, and the districts of Neuwied, Mayen-Koblenz and Vulkaneifel.

The Government Bunker (Regierungsbunker) in Germany, officially named Ausweichsitz der Verfassungsorgane des Bundes im Krisen- und Verteidigungsfall zur Wahrung von deren Funktionstüchtigkeit (AdVB), in English: "Emergency Seat of the Federal Constitutional Organs for the State of Crisis or State of Defence to Maintain their Ability to Function" was a massive underground complex built during the Cold War era to house the German government, parliament and enough federal personnel needed to keep the government working in the event of war or severe crisis. Located only about 25 kilometres (16 mi) south of Bonn, Germany (the government seat of pre-unification West Germany), in the Ahr Valley between the towns of Ahrweiler and Dernau, it was one of the best kept secrets of West Germany. It was built between 1960 and 1972 inside two abandoned railway tunnels that were built as part of the Strategic Railway, maintained and kept in a working condition for about 30 years and decommissioned in 1997. A small part of the once-secret site is now open to the public as Government Bunker Documentation Site, while the vast majority is abandoned and sealed.

The Ahr valley (German: Ahrtal, pronounced [ˈaːɐ̯taːl]) is named after the Ahr, a left tributary of the Rhine in Germany. It begins at the Ahr spring (Ahrquelle) in Blankenheim in the county of Euskirchen (North Rhine-Westphalia) and runs generally eastwards. At its southernmost point it enters the county of Ahrweiler, and hence the state of Rhineland-Palatinate. Running through the collective municipality of Adenau the valley bends northeast at its confluence with the Adenauer Bach and reaches the collective municipality of Altenahr, from where it resumes its characteristic west to east course, albeit interrupted by meanders. Here begins the section that is known as the Ahr valley (Ahrtal) in a touristic sense. Here it is characterized by vineyards on the south-facing slopes and a picturesque rocky landscape, carved out by the river creating a 300 metre deep gorge in the Ahr Hills. In the next stage the Ahr reaches the area of the county town of Bad Neuenahr-Ahrweiler, before finally discharging into the Rhine south of Remagen in the borough of Sinzig.

The Tracking & Imaging Radar (TIRA) system serves as the central experimental facility for the development and investigation of radar techniques for the detection and reconnaissance of objects in space, and (to a certain degree) of air targets. TIRA has a 34-metre parabolic dish antenna is a monopulse radar operating at 1.333 GHz or 22.5 cm (L band) and 16.7 GHz or 1.8 cm (Ku band) wavelengths. The L-band is usually used for tracking debris with a 0.45° beam width, at 1 MW peak power. The system is capable of determining orbits from direction angles, range and Doppler shift for single targets. The detection size threshold is about 2 cm at 1000 km range. The radar conducts regular ‘beam park’ experiments, where the radar beam is pointed in a fixed direction on the celestial sphere for 24 hours, scanning 360° in a narrow strip a complete Earth rotation. The tracking sensitive can be enhanced when the TIRA system is used as a transmitter, part of a bistatic radar system. In conjunction with the Effelsberg Radio Telescope, functioning as a receiver, the combined system has a detection size threshold of 1 cm. The Ku-band is used for imaging in Inverse Synthetic Aperture Radar (ISAR) mode, with 13 kW peak power, the radar is capable of producing images with range resolutions better than 7 cm. The dish can be turned full 360° in azimuth with speed of 24° per second and 90° in elevation. The radar is protected by a radome with 47 meters diameter – one of the largest in the world. Due to its capabilities, the system is used as a radar tracking system for space debris and other in-orbit object in the ESA's Space Situational Awareness Programme (SSA).TIRA is located at the FGAN (50.6166°N 7.1296°E / 50.6166; 7.1296) site, in Wachtberg near Bonn, Germany. It is run by the Fraunhofer-FHR – the Fraunhofer-Institut für Hochfrequenzphysik und Radartechnik (High Frequency Physics and Radar Techniques).

Wachtberg is a municipality in the Rhein-Sieg district, of North Rhine-Westphalia, Germany. It is situated approximately 15 km south of Bonn. In 2021 the Wachtberg municipality had approximately 20,352 inhabitants. The municipality was formed 1969 as a merger of 13 now incorporated villages. The town-hall is in the village of Berkum, approximately in the center of the area. The Rodderberg mountain is in the east of the Wachtberg district. The municipality is named after another volcanic mountain, the Wachtberg, (extinct for 25 million years, now with a height of 258 m) that is situated near the centre of the municipality.

It was the homeground of former Women's Bundesliga team SC 07 Bad Neuenahr until the dissolvement of the club in 2013. Since then, the ground is used by its successor club SC 13 Bad Neuenahr which is playing in the Regionalliga Südwest, the third-tier league in German women's football.

Ahr is a wine region (Anbaugebiet) for quality wine in Germany, and is located in the valley of the river Ahr, a tributary of Rhine, and is situated in the federal state of Rhineland-Palatinate. With only 558 hectares (1,380 acres) of vines as of 2008, it is one of smaller of Germany's 13 regions. Despite its northern location (it is for example situated north of Mosel region) it primarily produces red wines, and red grape varieties account for 86% of the vineyard area, which is more than in any other German wine region.
