Up to now I've got the best results with HTTrack. It Includes the sidebar on most of the pages. Just a pity that it doesn't show pictures that have  their size adapted (e.g. [File:Francis Franck.jpeg|left|200x640px| ]).

It think we can close the case here.
  Thanks again for your reactions.

Because of its relation with the cities' history I would like to get the wiki stored in the Archive of the city of Alkmaar but the problem is that they are not equipped for a Mediawiki-oriented structure. The require a fully html oriented version.

mwoffliner builds on the Parsoid output.

Parsoid only handles the page content, not the chrome, so it won't give you the sidebar, etc.

Please see above linked discussion for some ideas on how to make html dumps of your wiki.
