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).

The Aloisiuskolleg is a co-educational, Jesuit (Catholic), University-preparatory school in Bonn-Bad Godesberg, Germany, which includes boarders. It is named for Saint Aloysius Gonzaga. Highly ranked academically, it is considered one of the most prestigious boarding schools in Germany. Since early 2010 the school has been investigated for cases of child abuse.

King Fahd Academy (German: König-Fahd-Akademie, Arabic: أكاديمية الملك فهد بألمانيا. بون) was a school in Lannesdorf, Bad Godesberg district, Bonn, Germany. The school, with an attached mosque, housing elementary school through high school, opened in 1995. Financed by the King of Saudi Arabia and sponsored by Saudi Arabia, it was named after King Fahd. The school was closed at the end of the 2016/2017 school year, after long-running criticism that it was attracting Islamists to Germany. The school's last director was Ibrahim Al-Megren.

The destruction of the Oberstift, which included Linz, Ahrweiler, and other small towns and villages, occurred in the opening months of the Cologne War, from Christmas Day, 1582 until the end of March, 1583. Over these few weeks, armies of the competing archbishops of Cologne burned the southernmost villages, cloisters, and small towns. In the Cologne War (1583–1589) two men competed for control of the Electorate of Cologne and sought to control one of the wealthiest Electorates in the Holy Roman Empire. Their contest lasted until 1589, when Gebhard Truchsess von Waldburg renounced his claim and moved to Strassbourg; Ernst of Bavaria became uncontested Prince elector of Cologne, the first Wittelsbach to hold the position; his family maintained their hold on it until 1761. Under his direction, Jesuits introduced the Counter-Reformation to the north-western German states and under the leadership of his successors, these territories remained a Catholic stronghold until the late eighteenth century.

The Redoute in Bad Godesberg, now part of Bonn, North Rhine-Westphalia, Germany, is a hall opened in 1792 for balls of the court of Archduke Maximilian Francis of Austria. When Bonn was the location of the government of the Federal Republic of Germany, from 1949 to 1990, state receptions were held at the Redoute. Today, the listed historical building is used for events.
