Hello,
There are know three monuments projects on Commons.
A Nederland one, a French one and the last Portuguese one.
Objectives are to place médias on right categories and geotagged them.
See the template specialy created for:
http://commons.wikimedia.org/wiki/Template:Rijksmonumenten
http://commons.wikimedia.org/wiki/Template:Mérimée
http://commons.wikimedia.org/wiki/Template:IGESPAR
These projects are also like a bridge from Wikipedias.
I assume that could help newcomers.
