Où sont les prisons ? Belgique

Hi @joost_schouppe
I used data from https://justice.belgium.be/fr/themes_et_dossiers/prisons/prisons_belges in French because it was just easier for me to follow the information.

Thanks for Termonde, updated.

FPC facilities. Prison hospitals are still prisons for me.

As for licensing: User importing prison-names from official websites and sometimes deleting valid stuff (by mistake) - #10 by saldenisov. I have decided to stop inserting data myself. I will provide the data to local communities.

Thanks for your work!

best,
Sergey
