A heart tree is a tree with a carved face that followers of the old gods pray, often within a godswood. It is often said that no man can tell a lie in front of a heart tree, as the old gods know when men are lying. Heart trees are almost always weirwood trees, but other types of trees are used if weirwoods are not available. For instance, the godswood of the Red Keep in King's Landing is a great oak.
|“||Here every castle had its godswood, and every godswood had its heart tree, and every heart tree its face.||”|
|“||The heart tree had always frightened him; trees ought not have eyes, Bran thought, or leaves that looked like hands.||”|
