Geography
The municipality consists of the following districts: Bierset, Grâce-Berleur, Hollogne-aux-Pierres, Horion-Hozémont, and Velroux.

History
Grâce-Hollogne was formed by the grouping of former municipalities Bierset, Grâce-Berleur, Hollogne-aux-Pierres, Horion-Hozémont, and Velroux, along with part of Mons-lez-Liège.

The killing of four demonstrators on 30 July 1950 in Grâce-Berleur was one of the most significant moments in the so-called Royal Question of 1950, which grew out of resentment towards King Leopold III and his actions in World War II.

In June 1995 it was from Grâce-Hollogne that Julie Lejeune and Mélissa Russo were infamously abducted to become victims of the notorious serial killer and child molester Marc Dutroux. One of the municipality's schools is now named École Julie et Melissa in honour of the murdered girls, and flowers are still left regularly on the Julie & Melissa Monument.

Economy
Avient Aviation has its Continental Europe offices on the property of Liège Airport.
