No, they are two different but related concepts. It should be pointed out that the godwood at the Red Keep and maybe other Southern castles do not have Weirwood in them but have a normal tree as the heart tree.

I'd rather note that difference at the "main" article rather than have so many short articles(I dont like one line articles, if you haven notices ;) ), but if you prefer it this way, I am fine with .

Weirwoods in the south
"In the North every castle has a weirwood heart tree with a face. South of the Neck, however, most weirwoods were cut down or burnt years ago, with the only significant number on the Isle of Faces."
That sentence may be a little misleading, as it makes it sound like weirwood heart trees are uncommon in the south. Of all the castles we see in the south only two are confirmed to not have weirwood heart trees.(The Red Keep, and the Eyrie which technically isn't even a godswood) Even Harrenhal, built relatively recently by people who don't worship the old gods has a weirwood heart tree. --RumHam 15:38, 18 April 2014 (UTC)
