Nowadays, the city has several neighbourhoods: the old Hombourg, the old village of Hellering, urban areas with HLMs built in the 1950s-1960s and residential district.

In 1270, the bishop, Jacques of Lorraine, decided to build a new and splendid castle on the opposite elongated hill, probably from 1245 on.

In front of the castle, Jacques of Lorraine got a fortified town built, surrounded by a long wall, today's "Vieux-Hombourg".

[3] Jacques granted his new town privileges and rights and in 1254, he founded a collegiate church with 13 capitular canons that was run until 1743.

Providing employment to generations of Hombourg's inhabitants, the Gouvy steel mill also supported music, sports, youth movements and other leisure activities.
