The Great Saint Martin Church (German: Groß Sankt Martin, mostly shortened to Groß St. Martin, pronounced [ˈɡʁoːs ˌzaŋt ˈmaʁtɪn] (listen) or [- maʁˈtiːn] (listen), Colognian: [ˈjʁus² ˌtsɪnt ˈmɛ²təs] (listen)) is a Romanesque Catholic church in Cologne, Germany. Its foundations (c.960 AD) rest on remnants of a Roman chapel, built on what was then an island in the Rhine. The church was later transformed into a Benedictine monastery. The current buildings, including a soaring crossing tower that is a landmark of Cologne's Old Town, were erected between 1150-1250. The architecture of its eastern end forms a triconch or trefoil plan, consisting of three apses around the crossing, similar to that at St. Maria im Kapitol. The church was badly damaged in World War II; restoration work was completed in 1985. As of 2009 Great Saint Martin is being used by a branch of the Monastic Fraternities of Jerusalem and is open for visits again.

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.

The Hohenzollern Bridge (German: Hohenzollernbrücke) is a bridge crossing the river Rhine in the German city of Cologne (German: Köln). It crosses the Rhine at kilometre 688.5. Originally, the bridge was both a railway and road bridge. However, after its destruction in 1945 and its subsequent reconstruction, it was only accessible to rail and pedestrian traffic. It is the most heavily used railway bridge in Germany with more than 1,200 trains daily, connecting the Köln Hauptbahnhof and Köln Messe/Deutz stations.

Lintgasse is an alley (German: Gasse) in the Old town of Cologne, Germany between the two squares of Alter Markt and Fischmarkt. It is a pedestrian zone and only some 130 metres long, nevertheless famous for its medieval history. The Lintgasse was first mentioned in the 12th century as »in Lintgazzin«, which may have derived from basketmakers described, weaving fish baskets out of Linden tree barks. These craftsmen were called »Lindslizer«, meaning Linden splitter. During the Middle Ages, the area was also known as »platēa subri« or »platēa suberis«, meaning street of Quercus suber. Lintgasse 8 to 14 used to be homes of medieval knights as still can be seen by signs like »Zum Huynen«, »Zum Ritter« or »Zum Gir«. At Lintgasse 15 once stood the Parish of St. Brigiden, which became an elementary school during the 19th century. During this time, the Lintgasse was called »Stink-Linkgaß«, as the alley was unpopular for its poor air quality. Lintgasse 9 has a passage to the nearby Great St. Martin Church. On the corner of Alter Markt and Lintgasse stands the listed Gaffel-Haus »Zur Brezel«. The brewhouse is a 7-storey Dutch Renaissance townhouse, built in 1213 but substantially extended in 1580. The building was a significant place in the history of Cologne and only converted into a beer house in the late 19th century.

The Cathedral Bridge (German: Dombrücke, pronounced [ˈdoːmˌbʁʏkə]) was a railway and street bridge crossing the river Rhine in the German city of Cologne. It was owned by the Cologne-Minden Railway Company and named after the Cologne Cathedral, which is located on the same longitudinal axis. It was built in combination with the original Central Station (German: Zentralbahnhof [tsɛnˈtʁaːlˌbaːnhoːf]) and a new ground-level railway track through the north Altstadt of the Cologne Innenstadt. As the Cathedral Bridge could not bolster the increased traffic of the new Köln Hauptbahnhof in 1894, it was replaced by the Hohenzollern Bridge in 1911. The Cathedral Bridge was the second railway bridge to be built over the river Rhine, after the significantly shorter Waldshut–Koblenz Rhine Bridge with spans of up to 52 metres (171 ft), which was opened just a few months prior on 18 August 1859.
