Hollerich was first mentioned in a document in the 10th century.^[3] In the course of the French administrative reorganisation of 1796, it achieved the status of a separate commune.^[3] In 1859, Luxembourg's railway station was built on the commune's territory.^[3] This facilitated its modern development from a farming village located at the Petrusse and the road towards Esch, to an important industrial site in front of the gates of Luxembourg City.^[3]

Soon, the commune attracted industries due to its good infrastructure: the iron industry with Paul Würth from 1891, champagne production with mit Mercier as well as the tobacco producer Heinz von Landewyck, to name only a few.^[3]

Hollerich was a commune in the canton of Luxembourg until 26 March 1920, when it was merged into the city of Luxembourg, along with Hamm and Rollingergrund.^[4] From 7 April 1914 until the dissolution of the commune, the part of the commune encompassing the urban areas of Hollerich and Bonnevoie was afforded the title of city. The title was not conferred upon all of the commune; the part that was granted the title was officially styled 'Hollerich-Bonnevoie'.^[5]

It is also the location of Den Atelier, a music venue.
