For particular sacred groves, and for other meanings, see Sacred grove (disambiguation).A sacred grove or sacred woods are any grove of trees of special religious importance to a particular culture. Sacred groves feature in various cultures throughout the world.They were important features of the mythological landscape and cult practice of Celtic, Baltic, Germanic, ancient Greek, Near Eastern, Roman, and Slavic polytheism, and were also used in India, Japan, and West Africa. Examples of sacred groves include the Greco-Roman temenos, the Norse hörgr, and the Celtic nemeton, which was largely but not exclusively associated with Druidic practice. During the Northern Crusades, there was a common practice of building churches on the sites of sacred groves. The Lakota and other Various tribes consider particular forests or other natural landmarks to be sacred. This is one of the reasons that there has been recent dispute over the nullification of acknowledgment of native American reservation land by the US government and an attempt to compensate Native Americans for the reacquisition of this sacred space.Ancient holy trees still exist in the English countryside and are mentioned often in folklore and fairytales.
