Prison H11 is an abandoned, multi-level building in Liege, Belgium, characterized by extensive decay and neglect. The interior features long, narrow hallways with peeling paint, graffiti-covered walls, and geometric gray and white floor tiles. Metal staircases connect the levels, including a black metal bar staircase that has partially collapsed. The facility contains rooms with concrete and tile floors covered in debris, rubble, and dirt. Structural elements include walls stripped to their bare structure, broken boards, and holes leading between sections of the building. Notable details within the rooms include broken windows, pipes running along walls, a "No Smoking" sign in a dilapidated bathroom with missing white tiles, and an old chair covered in dust and cobwebs. Stacked white boxes, one of which is damaged, and scattered metal debris are also found within the site.
