St. Maria in der Kupfergasse

EL-DE Haus, officially the NS Documentation Center of the City of Cologne, located in Cologne, is the former headquarters of the Gestapo and now a museum documenting the Third Reich. The building was at first the business premises of jeweller Leopold Dahmen, and the building takes its name from his initials. In 1934, the Nazis rented the building from him and turned it into the headquarters of the secret police, the Gestapo. Surprisingly, the building survived the Allied bombing of Cologne during World War II, while 90% of the city was destroyed. After the bombings, the basements of the building, which had been used as prison cells and torture rooms for forced labourers and political enemies, were used to store wartime files and paperwork. Inscriptions made on the walls of the prison cells by inmates can still be viewed today. The building was the site of many executions, as well as deaths due to overcrowding and poor hygienic conditions. In 2006, the Documentation Centre on National Socialism was awarded the Best in Heritage award, which is given to select museums. The only other German museum to have won the prize is the Buddenbrook Museum in Lübeck.

Theater am Dom is a theatre in Cologne, North Rhine-Westphalia, Germany.

The Kölnische Stadtmuseum is the municipal history museum of Cologne, North Rhine-Westphalia, Germany. It is housed in the building of the historic Zeughaus with the adjacent Prussian Alte Wache Zeughaus. Its collection includes around 350,000 objects from the Middle Ages to the immediate present. The holdings range from the city seal from 1268 to paintings and graphics, militaria, coins, textiles, furniture and everyday objects to material evidence of current Cologne events. Social, economic and cultural history of the last 1200 years can thus be explored both on the individual object and in thematic depth. Annual visits in 2018 were 19,832, although the museum has had to do without its permanent exhibition since 2017, as the armoury is no longer usable following water damage. Special exhibitions continue to be presented regularly in the Alte Wache; the move to interim quarters is imminent. Unlike in other cities, about half of the audience is registered in Cologne, which has been interpreted as an indication of Cologne's attachment to its homeland.In its more than 130-year history, the Stadtmuseum has resided under different names and in different buildings in the city area. The current location is also expected to be replaced in favour of a new building in the "Historische Mitte" near the Cologne Cathedral.

The Synagogue in Glockengasse was a synagogue in Cologne built to the plans of the architect of the Cologne Cathedral, Ernst Friedrich Zwirner. It was built on the previous Monastery of St. Clarissa, where a modest hall of prayer had been erected in the years of the French occupation and had been closed in 1853 because it was unsafe.On June 10, 1856, after much discussion in the Jewish communal executive board about whether it was better to build a synagogue in the same or a different spot, Abraham Oppenheim, son of Salomon Oppenheim, Jr., announced his readiness to erect a synagogue worthy of the Glockengasse at his own cost as a gift to the community. Drucker-Emden, a member of the Jewish communal administration, supported the decision. The cornerstone was laid on June 23, 1857. On August 29, 1861, there was a procession from the provisional synagogue on St. Apernstrasse along Breitestrasse and Kolumbastrasse to the new synagogue. The synagogue was dedicated to Rabbi Israel Schwarz. A memorial tablet dedicated to the donor was placed inside and a medal of silver and bronze was struck.In June 1867, fire damaged the building. In the same year Albert, the son of Simon Oppenheim, Abraham’s brother, and his wife sold a piece of land on the south side of the synagogue and a strip on the east to the Jewish community, making it possible to enlarge the synagogue, erect a smaller synagogue for week-day services, and leave room for a court.The fiftieth anniversary of the synagogue was celebrated in 1911. During World War I, the large cupola, as well as the smaller ones, were stripped of their original copper covering. The cupolas had been regarded as among the most beautiful in Cologne because of the patinated copper. In consequence of the removal, the four towers on the outside pillars were dismantled and only restored in 1925, while the replacement of the copper covering was postponed for financial reasons. The synagogue was destroyed during the Kristallnacht on November 9, 1938 together with the other synagogues in Cologne. The modernist Cologne Opera House now occupies the site. A bronze plaque on its façade on Offenbachplatz commemorates the synagogue. The synagogue has been recreated in virtual form.

The Schildergasse (German: [ˈʃɪldɐˌɡasə]; Kölsch: Schelderjaß [ˌʃel²dɐˈjasˑ]) is a shopping street in central Cologne, Germany. With 13,000 people passing through it every hour, it is the busiest shopping street in Europe, according to a 2008 survey by GfK. The Schildergasse is a designated pedestrian zone and stretches for about 500 meters from the Hohe Straße at its eastern end to the Neumarkt at the western end. The street dates back to Roman times, when it was the city's Decumanus Maximus. During the Middle Ages it was home to many artists who painted heraldic coats of arms, whence the street's name (Schilder means signs or escutcheons). Among today's landmarks on Schildergasse are the Atoniterkirche, the oldest Protestant church in Cologne, and Peek & Cloppenburg's Weltstadthaus, designed by Renzo Piano.

St. Andrew's (German: St. Andreas) is a 10th-century Romanesque church located in the old town of Cologne, Germany. It is one of twelve churches built in Cologne in that period.Archbishop Gero consecrated the church in 974, dedicating it to St. Andrew, although an earlier church at the site was dedicated to St. Matthew. In the 12th century, the church was rebuilt in the Romanesque style, and was probably completed after the great fire of Cologne in 1220. In the crypt of the church lies a Roman sarcophagus from the 3rd century, which holds the remains of the 13th-century theologian and natural philosopher St. Albertus Magnus. Since 1947, the Dominican Order has ministered to the church.

St. Kolumba was one of the largest parish churches in medieval Cologne, dating back to 980, and dedicated to Columba of Sens. The original Romanesque church was replaced by a Gothic church. Artworks in it included the Saint Columba Altarpiece by Rogier van der Weyden, and an altar by an anonymous artist. It was almost completely destroyed by bombing in World War II. From 1947, a chapel was built on the ruins, dedicated to Mary as "Madonna of the Ruins". The chapel was called St. Kolumba from 2007, when it became part of the Kolumba, the museum of the archdiocese of Cologne.

Cologne (English: kə-LOHN; German: Köln [kœln] (listen); Kölsch: Kölle [ˈkœlə] (listen)) is the largest city of Germany's most populous state of North Rhine-Westphalia (NRW) and the fourth-most populous city and one of the oldest in Germany. With 3.6 million people in the urban region and 1.1 million inhabitants within its city proper, Cologne is the largest city on the river Rhine and also the most populous city of both the Rhine-Ruhr Metropolitan Region and the Rhineland. Centered on the left (west) bank of the Rhine, Cologne is about 35 km (22 mi) southeast of NRW's state capital Düsseldorf and 25 km (16 mi) northwest of Bonn. The city's medieval Catholic Cologne Cathedral (Kölner Dom), the third-tallest church and tallest cathedral in the world, constructed to house the Shrine of the Three Kings, is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne, and Cologne is famous for Eau de Cologne, that has been produced in the city since 1709, and "cologne" has since come to be a generic term. There are many institutions of higher education in the city, most notably the University of Cologne, one of Europe's oldest and largest universities; the Technical University of Cologne, Germany's largest university of applied sciences; and the German Sport University Cologne. It hosts three Max Planck science institutes and is a major research hub for the aerospace industry, with the German Aerospace Center and the European Astronaut Centre headquarters. It also has significant chemical and automobile industry. Cologne Bonn Airport is a regional hub, the main airport for the region is Düsseldorf Airport. Cologne was founded and established in Germanic Ubii territory in the 1st century CE as the Roman Colonia Agrippina, hence its name (Augusta Ubiorum was also used). "Agrippina" was later dropped (except in Latin), and "Colonia" became the name of the city in its own right, which developed into modern German as Köln. "Cologne", the French version of the city's name, has become standard in English as well. Cologne functioned as the capital of the Roman province of Germania Inferior and as the headquarters of the Roman military in the region until occupied by the Franks in 462. During the Middle Ages the city flourished as being located on one of the most important major trade routes between east and western Europe (including the Brabant Road, Via Regia and Publica). Cologne was a free imperial city of the Holy Roman Empire and one of the major members of the trade union Hanseatic League. It was one of the largest European cities in medieval and renaissance times. Prior to World War II, the city had undergone occupations by the French (1794–1815) and the British (1918–1926), and was part of Prussia beginning in 1815. Cologne was one of the most heavily bombed cities in Germany during World War II. The bombing reduced the population by 95%, mainly due to evacuation, and destroyed almost the entire millennia-old city center. The post-war rebuilding has resulted in a very mixed cityscape, restoring only major historic landmarks like city gates and churches (31 of them being Romanesque). Cologne is a major cultural center for the Rhineland; it hosts more than 30 museums and hundreds of galleries. Exhibitions range from local ancient Roman archeological sites to contemporary graphics and sculpture. The Cologne Trade Fair hosts a number of trade shows such as Art Cologne, Dmexco, imm Cologne, Photokina and Gamescom, a leading video games fair.

The Cisrhenian Republic (German: Cisrhenanische Republik) was a client state (sister republic) of the French Revolutionary Wars. It was proclaimed in 1797 on the Left Bank of the Rhine under French occupation.
