Kirchberg is the predominant location of the European Union institutions and bodies based within Luxembourg, and is sometimes used as a metonym for the EU's judiciary, which occupies the quarter.

Although Kirchberg is first mentioned in historical records in 1222, one may assume there was an earlier settlement there, due to its useful location close to the Roman road from Reims to Trier.

In that year, the historian Nicolas van Werveke declared in a speech: "Who among us does not know the Kiem of Grünewald, [...] it is so well preserved on the whole stretch of the plateau, to the point where it leaves the forest, that one may boldly consider this part of the road one of the best-preserved of Gaul."

In 1875, the Parish Church of Our Lady, Refuge of the Sick[nb 1], was built to serve a small farming community that had established themselves in central Kirchberg.

[7] The avenue was beautified from its original inception as an expressway into a tree-lined pedestrian-and-cycle-friendly thoroughfare, with separated tram and bus lanes.

The partially reconstructed Fort Thüngen, listed along with the rest of the former Fortress of Luxembourg, as a UNESCO World Heritage Site, hosts the Mudam, a museum of modern art opened in 2006.

In close proximity, adjacent to one of the European Parliament's original plenary chambers, is the Philharmonie, Luxembourg's national concert hall.

[14] Like Luxembourg City, Kirchberg has a general oceanic climate (Köppen: Cfb), marked by high precipitation, particularly in late spring.

However, the slope and height of the area accounts for occasional lower temperatures (up to 1° below Luxembourg City), more frequent fog and enhanced precipitation of both rain and snow.
