Shrine of the Three Kings

The Judensau at the choir stalls of Cologne Cathedral is a medieval, antisemitic wood carving at the side of one of the seats in the choir of Cologne Cathedral. It was produced between 1308 and 1311. It shows a Jews' sow, a folk art image of Jews in obscene contact with a large female pig, which in Judaism is an unclean animal. It is one of the oldest representations of this theme. Directly beside is another antisemitic motif, which is generally interpreted as an illustration of the blood libel legend. This combination is only known from one other case, a painting from the 15th century at the Old Bridge in Frankfurt. The cathedral chapter and mason's lodge of the cathedral want to keep and display the wood carvings at their original position. This decision has been controversially discussed and criticised by parts of the public on several occasions, although the sculptures may only be accessed by permission within bespoke guided tours.

It was inhabited by members of the Cologne Cathedral Chapter and was a emphyteusis of the cathedral monastery. Today, the area is part of the grounds of the Romano-Germanic Museum.

Cologne Cathedral (German: Kölner Dom, officially Hohe Domkirche Sankt Petrus, English: Cathedral Church of Saint Peter) is a Catholic cathedral in Cologne, North Rhine-Westphalia. It is the seat of the Archbishop of Cologne and of the administration of the Archdiocese of Cologne. It is a renowned monument of German Catholicism and Gothic architecture and was declared a World Heritage Site in 1996. It is Germany's most visited landmark, attracting an average of 20,000 people a day. At 157 m (515 ft), the cathedral is currently the tallest twin-spired church in the world, the second tallest church in Europe after Ulm Minster, and the third tallest church in the world. It is the largest Gothic church in Northern Europe and has the second-tallest spires. The towers for its two huge spires give the cathedral the largest façade of any church in the world. The choir has the largest height-to-width ratio, 3.6:1, of any medieval church.Construction of Cologne Cathedral began in 1248 but was halted in the years around 1560, unfinished. Work did not restart until the 1840s, and the edifice was completed to its original Medieval plan in 1880.Cologne's medieval builders had planned a grand structure to house the reliquary of the Three Kings and fit its role as a place of worship for the Holy Roman Emperor. Despite having been left incomplete during the medieval period, Cologne Cathedral eventually became unified as "a masterpiece of exceptional intrinsic value" and "a powerful testimony to the strength and persistence of Christian belief in medieval and modern Europe". Only the telecommunications tower is higher than the Cathedral.

The Cologne Cathedral Window is the stained glass window in the south transept of the Cologne Cathedral designed by Cologne artist Gerhard Richter. On a surface of 106 square metres 11.263 glass squares in 72 colours of 9,6 cm × 9.6 cm were principally arranged randomly, with others selected in response to architectural context. The window was inaugurated on August 25, 2007 as part of a Eucharistic celebration; the abstract execution was both celebrated and strongly criticized.

The Roman-Germanic Museum (RGM, in German: Römisch-Germanisches Museum) is an archaeological museum in Cologne, Germany. It has a large collection of Roman artifacts from the Roman settlement of Colonia Claudia Ara Agrippinensium, on which modern Cologne is built. The museum protects the original site of a Roman town villa, from which a large Dionysus mosaic remains in its original place in the basement, and the related Roman Road just outside. In this respect the museum is an archaeological site. The museum also has the task of preserving the Roman cultural heritage of Cologne, and therefore houses an extensive collection of Roman glass from funerals and burials and also exercises archaeological supervision over the construction of the Cologne underground. Most of the museum's collection was housed at the Wallraf-Richartz Museum in Cologne until 1946. In the front of the museum the former northern town gate of Cologne with the inscription CCAA (for Colonia Claudia Ara Agrippinensium) is on display in the building.

St. Maria ad Gradus ("Our Lady of the Steps", also colloquially called Mariengraden in German language) is the name of a former church located East of the Cathedral of Cologne, Germany, situated between the cathedral and the Rhine. Founded by Herman II, Archbishop of Cologne, the church was the burial site of blessed Richeza of Lotharingia (died March 1063), a former Queen of Poland and a grandchild of Otto II, Holy Roman Emperor and his wife Theophanu. The Romanesque building, 55m long and 42m wide, was probably completed by Archbishop Anno II in 1075, when the relics of St. Agilulfus of Cologne (died 750) were transferred there. Already in 1080 it burned down, but was rebuilt in 1085 and later expanded.The remains of Richeza and others were later translated to the cathedral, which had been begun in 1248. Konrad von Hochstaden was canon of St. Maria ad Gradus and Archbishop of Cologne at this time, from 1238 to 1261. Following the French occupation of the Rhineland in 1794, monasteries and religious foundations were dissolved, and churches abandoned. As St. Maria ad Gradus was too close to other churches (the Cathedral, Great St. Martin's, and St. Andreas), it was partially demolished in 1817; and most of what remained was removed in 1827 when the area was cleared to allow the Cathedral's restoration and completion. Only a few fragments remain.

Over 1,200 women were reportedly sexually assaulted during the 2015–16 public New Year's Eve's celebrations in Germany, in most cases by men of non-European origin. Multiple women reported being raped. In many of the incidents, women in public places had been surrounded and assaulted by groups of men. The Bundeskriminalamt (German Federal Criminal Police) confirmed in July 2016 that 1,200 women had been sexually assaulted on that New Year's night.By 4 January 2016, the German national media reported that in Cologne, the sexual assaulters had mostly been described as "North African", "Arab", "dark-skinned" and "foreign". On 5 January 2016, the German government and the Cologne police speculated that the attacks might have been organized. However, by 21 January, the North Rhine-Westphalian government declared that there were no indications of premeditated organized attacks, and on 11 February, the new Cologne police president stated the same. Instead, the Cologne police chief suggested that the perpetrators had come from countries where such sexual assaults by groups of men are common. That suggestion was confirmed in a Federal Criminal Police report in June 2016, which also identified five more factors contributing to the occurrence of the attacks: group pressure, absence of police intervention, frustrations of migrants, disinhibition caused by alcohol and/or drug use, and disinhibition due to lack of social ties with German society.By April 2016, statistics recorded by authorities indicated that out of the identified 153 suspects in Cologne who were convicted of sexual offenses and other crimes during New Year's Eve 2015–16, two-thirds were originally from Morocco or Algeria, 44% were asylum seekers, another 12% were likely to have been in Germany illegally, and 3% were underaged unaccompanied refugees. By July 2016, the police stated that half of the 120 identified suspects of sexual offences on the New Year's Eve had arrived in Germany during the year 2015, most of those 120 had come from North Africa, and four suspects nationwide had been convicted. By November 2016, around 200 suspects of the sexual assaults had been identified nationwide.
