A Druid's Circle is a popular name for circles of standing stones such as Stonehenge, which is the most famous example. These are also known as the "Temples of the Druids". Great mounds of earth were also built where the practice of seeking rebirth within the Earth was performed (in which initiates would sit in darkness awaiting the time of their rebirth). The best example of this is found at New Grange in Ireland, where a shaft is oriented to the Winter Solstice sunrise, so that the dawn rays can bathe the initiate in sunlight after his or her vigil through the night.
