We had the same problem for the Portuguese coordinates that were in IGeoE Hayford Gauss format, a national format, but I used ArcGIS to transform the coordinates, which seems to be accurate. If anybody else needs to convert coordinates, just send them to me (preferably in DBase IV format, but Excel is also ok) and I will return them in WGS84 format.

By the way, check http://wlm.wikimedia.pt/monumentos.php for our monuments map.

Wikimapia has some buildings geolacated. Not a solution, but it may help in some cases.

A problem we have encountered is that local administrations in Spain are using coordinates in UTM ED50 format. We use a spreadsheet to convert them into GPS format, but it is not precise enough for landmarks. Geohack does not have UTM ED50 format.
