===Urban districts===
Unlike the Dortmund city centre, much of the inner districts around the old medieval centre escaped damage in the second world war and post war redevelopment.

====Kreuzviertel====
[[File:Kreuzstraße.JPG|thumb|Typical Wilhelminian style houses]]
The [[Kreuzviertel]] is characterised by old buildings, the majority of which come from the turn of the 20th century (1884 to 1908). Over 80% of all housing in this area was constructed before 1948, with the oldest building the Dortmund University of Applied Sciences and Arts still standing being from 1896. In the [[Second World War]], relatively few buildings were destroyed in comparison to other areas of the city. Today, [[Kreuzviertel]] forms a nearly homogeneous historic building area. Over 100 buildings remain protected as historic monuments, like the Kreuzkirche at Kreuzstraße and the first concrete church in Germany St.-Nicolai. Nowadays the Kreuzviertel is a trendy district with pubs, restaurants, cafés, galleries, and little shops. Moreover, local efforts to beautify and invigorate the neighbourhood have reinforced a budding sense of community and artistic expression. The West park is the green lung of the Kreuzviertel and in the months between May and October a centre of the student urban life. The district has the highest real estate prices in Dortmund.<ref>{{cite web |url=https://www.capital.de/immobilien-kompass/dortmund.html/ |title=Mietspiegel und Immobilienpreise von Dortmund &#124; Capital |access-date=29 November 2017 |archive-url=https://web.archive.org/web/20171228181111/https://www.capital.de/immobilien-kompass/dortmund.html#Szeneviertel |archive-date=28 December 2017 |url-status=dead |df=dmy-all }}</ref>

Even today many artists choose Kreuzviertel as their residence: [[Sasha (German singer)|Sascha Schmitz]], [[Christina Hammer]], and players of [[Borussia Dortmund]].

==== Nordstadt ====
[[File:Nordstadt_Dortmund_Hafenviertel.jpg|thumb|Dockland – young restaurant and bars scene]]
The northern downtown part of Dortmund called Nordstadt, situated in a territory of {{cvt|14.42|km2}} is shaped by a colorful variety of cultures. As the largest homogeneous old building area in [[Ruhr]] the Nordstadt is a melting pot of different people of different countries and habits just a few steps from the city center. The Nordstadt is an industrial [[urban area]] that was mainly developed in the 19th century to serve the [[Westfalenhütte]] steelworks, port and rail freight depot. All of the residents live in a densely populated 300 hectare area (the most densely populated residential area in the state of [[North Rhine-Westphalia]] with steelworks, port and railway lines acting as physical barriers cutting off the area from the city centre and other residential districts).<ref name="Dortmund.de">{{cite web|url=http://www.dortmund.de/de/leben_in_dortmund/stadtbezirke/stbzportal_innenstadtnord/leben_in_in//|title=Die Stadt im Wiederaufbau|website=Dortmund.de}}</ref>

The area has been badly affected by the deindustrialisation of these heavy industries, with the target area developing a role as the home for growing numbers of immigrants and socially disadvantaged groups partly because of the availability of cheaper (although poor quality) accommodation.<ref>{{cite web |url=http://www.spiegel.de/international/germany/dortmund-boosts-efforts-to-integrate-bulgarian-and-romanian-immigrants-a-911619.html// |title=Dortmund Boosts Efforts to Integrate Bulgarian and Romanian Immigrants - SPIEGEL ONLINE |access-date=2016-04-03 |url-status=dead |archive-url=https://web.archive.org/web/20160330025233/http://www.spiegel.de/international/germany/dortmund-boosts-efforts-to-integrate-bulgarian-and-romanian-immigrants-a-911619.html |archive-date=30 March 2016 |df=dmy-all }}</ref> Nevertheless, two parks – Fredenbaumpark and Hoeschpark – are situated there. There is also much equipment for children to spend their free time. For example, the 35 meters high Big Tipi, which was brought in from the [[Expo 2000]] in Hanover. All of that should attract families to settle in, but low prices of apartments and a variety of renting offers speak for the contrary. This developed into the youngest population of Dortmund is living and created a district with art house cinemas to ethnic stores, from exotic restaurants to student pubs.<ref name="Dortmund.de"/>

The Borsigplatz is probably one of the best known squares in Germany. Ballspielverein [[Borussia Dortmund]] was founded nearby, north-east of the main railway station. The streets radiating outward to form a star shape, the sycamore in the middle of the square and the tramline running diagonally across the square give Borsigplatz its very own flair.<ref>{{cite web|url=http://www.bvb.de/eng/BVB/History/1909//|title=BVB 09 – Back to our History – 1909 – Borussia Dortmund – bvb.de|website=Bvb.de}}</ref>

====Kaiserviertel====
[[File:Dortmund Kaiserstraßenviertel.jpg|thumb|Cherry Blossom Avenue]]
The Kaiserstraßen District is located east of the former ramparts of Dortmund and follows the course of the [[Westenhellweg]]. In this district numerous magnificent buildings from the 1900s and new buildings from the 1950s are located next to the heritage-protected State Mining Office Dortmund, several Courts, Consulate and the East Cemetery. The district is characterize by the employee of the Amtsgericht, Landgericht (the first and second instances of ordinary jurisdiction) and the Prison.

Today the historical Kaiserbrunnen and the entrance sign for Kaiserstraße are important starting points for a tour to the popular shopping district. The Moltkestreet also known as the Cherry Blossom Avenue, became famous after photographers started posting pictures of blooming trees. Every spring, usually in April, the street in the Kaiserstraßen district is booming with pink blossoms and attracts tourists.

====Unionviertel====
[[File:Unionviertel Dortmund.jpg|thumb|Rheinische Straße]]
The Union District is located west of the former ramparts of Dortmund and follows the course of the [[Westenhellweg]]. For a long time, the neighbourhood at the Dortmunder U and along the Rheinische Straße was marked by vacancy and social distortion due to structural change. Today it is developing an inspiring young artist scene, with more and more students thanks to cheaper apartments near the university and a vibrant gastronomy. This development benefits strongly from the new, widely visible beacon, the art and creative centre Dortmunder U, opened in 2010. Yet, for a time, it was mainly the Union Gewerbehof activists and other single stakeholders who initiated change.<ref>{{cite web|url=http://www.e-c-c-e.de/kreativquartiere-ruhr.html|title=ecce – european centre for creative economy: Kreativ.Quartiere Ruhr|website=E-c-c-e.de}}</ref>

====Hörde on Lake Phoenix====
[[File:Dortmund Hoerde Hoerder Burg 05.jpg|thumb|Hörde castle]]
Hörde is borough in the south of the city of Dortmund. Originally Hörde was a separate town (until 1929) and was founded by the Counts of Mark in opposition to their principal enemy, the town of Dortmund. In 1388, the "Großen Dortmunder Fehde" (great feud of Dortmund) took place, where the city of Dortmund battled against the alliance of surrounding towns. The struggle ended in 1390, with defeat for Hörde and its allies of [[Herdecke]], [[Witten]], [[Bochum]], [[Castrop]], [[Lünen]], [[Unna]], and [[Schwerte]]. Today Hörde is a part of Dortmund with restored old buildings combined with modern architecture. The Hörder Burg (Hörde castle) was built in the 12th century and is located in the east of the town, close to the [[Emscher]] and Lake Phoenix.

Lake Phoenix was one of the largest urban redevelopment projects in [[Europe]]. On the area of the former blast furnace and steel plant site of [[ThyssenKrupp]] newly formed and developed a new urban resident and recreational area {{convert|3|km|mi|frac=2|abbr=off|sp=us}} from the city centre of Dortmund. The development of the Phoenix See area cost €;170 million.<ref>{{cite web|url=http://www.eglv.de/en/emschergenossenschaft/emscher-conversion/the-new-emscher-valley/phoenix-lake/|title=Phoenix Lake|website=Eglv.de|access-date=17 February 2017|archive-url=https://web.archive.org/web/20190212014936/http://www.eglv.de/en/emschergenossenschaft/emscher-conversion/the-new-emscher-valley/phoenix-lake/|archive-date=12 February 2019|url-status=dead}}</ref> The lake is 1.2&nbsp;km long directed to east–west and 320 meters wide in north–south direction. The water surface area of 24 acres is larger than the [[Hamburg]] [[Alster]]. Lake Phoenix is a shallow water lake with a depth of 3 to 4 meters and a capacity of around 600,000 cubic meters. Attractive high priced residential areas were thus created on the southern and northern sides of the Lake. On the western lakeside, the existing district centre of Hörde is enlarged by a city port and a mixed functional urban area.

Companies with agencies and offices on the lakefront include:

*[[Zalando]]
*[[HSBC Trinkaus]]
*[[German Handball Association]]
*[[Handball-Bundesliga|Handball-Bundesliga (HBL)]]
*{{lang|de|Sparkassenakademie Nordrhein-Westfalen}}, a training organization of the [[Sparkasse (Germany)|Sparkassen]]
*[[Mircosonic]]

The finished sole is primarily fed by groundwater and unpolluted rainwater from the new building sites.<ref>{{cite web|url=https://www.dortmund.de/en/leisure_and_culture/phoenix_see_1/index.html|title=Phoenix-See – Leisure & Culture – dortmund.de|website=Dortmund.de}}</ref>
The River [[Emscher]] flows through an embanked riverbed without direct link to the Lake. Together with the renatured Emscher, the Lake forms a water landscape of 33 hectares, which, as a linking area, is an important element of the Emscher landscape park. The renaturation of the Emscher River is managed by the public [[water board]] [[Emschergenossenschaft]]. The financial frame is 4.5 billion Euro and the aim is to finish the main work by 2020.<ref>{{cite web|url=https://www.umwelt.nrw.de/umweltschutz-umweltwirtschaft/umwelt-und-wasser/abwasser/emscherumbau/|title=webpage Environment Ministry|access-date=14 September 2015|archive-url=https://web.archive.org/web/20151223023515/https://www.umwelt.nrw.de/umweltschutz-umweltwirtschaft/umwelt-und-wasser/abwasser/emscherumbau/|archive-date=23 December 2015|url-status=dead|df=dmy-all}}</ref>
