Heerdt
city district of Düsseldorf, Germany
Heerdt (German pronunciation: [heːɐ̯t]) is one of the older quarters of the city of Düsseldorf, part of Borough 4. Heerdt and its neighbouring quarters Oberkassel, Niederkassel and Lörick lie on the left side of the river Rhine, opposite to the other districts of Düsseldorf and the central district. Heerdt has an area of 4.05 km2 (1.56 sq mi), and 12,395 inhabitants (2020).
Heerdt is connected to the centre of the city by three bridges, the Oberkassler Brücke, the Rheinkniebrücke and the Theodor-Heuss-Brücke. Cars, bikes and pedestrians can use all bridges. The Oberkassler Brücke is used by some tram and underground lines running between the districts on both sides of the river. There is a direct connection to the motorway 52 heading to Krefeld and Mönchengladbach. The tram lines U70 and U76 connect Heerdt with Meerbusch and Krefeld (and the central districts, too), the line U75 with Neuss.
Heerdt was first mentioned in the 11th century. For centuries Heerdt was strongly connected to the neighbouring town of Neuss.
This brief starts where responsible research should: with the source description of “Heerdt” as city district of Düsseldorf, Germany. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as city district of Düsseldorf, Germany. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 13, 2025. The linked authority identifier is Q1551074. The first chronological checks are 2020.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
