A place mostly used for local events and festivities.
A public facility which is mostly used by local associations for events and festivities. Sometimes it can also be used for private or commercial events. See wikipedia:Community centre. Use an operator=*-Tag in conjunction to indicate who operates the facility.
These facilities are not used for administration or government purposes, so do not mix them up with the "townhall".
Uses around the world
In Germany we call it Bürgerhaus oder Dorfgemeinschaftshaus (in smaller village) or Stadthalle (in bigger towns). Almost every village or town in Germany has such a Community Centre. So it is a very important POI.
In Canada, we call it a community centre in English, or centre communautaire in French, a public building in which community gatherings and/or sporting activities are held. (Natural Resources Canada - CanVec Map Features Definition Code 2010080 (node) & 2010082 (area))
In France, we call it Salle des fêtes. Almost all the village have one like this, and you can rent it for weddings or other festivities.
In Italy there is centro sociale which corrisponds to this tag.
In Latin America is salón de fiestas y/o eventos. It's a place to rent for parties/events.
The proposal has been submitted to review (and approved) with the American spelling 'center'. But tags are until now using the UK (and Canada) version. To keep consistency, the proposal has been renamed 'community_centre'. http://en.wikipedia.org/wiki/Community_centre
