historic=ruins on a node not rendered

[PontiacCZ]

I wanted to add castle ruins to the OSM but to my surprise they already are in the map, just not rendered in Mapnik. I only added "ruins=castle" but it did not help anyway.

According to the Wiki page this tagging on a node should be okay. Or is it not?
