 The Hörgr was constructed of piled stones, possibly in a wood (harrow), and would be used in sacrifices and perhaps other ceremonies as well.A possible use of the hörgr during a sacrifice would be to place upon it a bowl of the blood of an animal sacrificed to a Norse deity (e.g.a goat for Thor, a sow for Freyja, a boar for Freyr), then dipping a bundle of fir twigs into it and sprinkling the participants with the blood.
