Factsheets : Cadet Chapel: "FALCON CIRCLE
The worship area known as the Cadet Chapel - Falcon Circle came about through a request from the Air Force Academy's followers of Earth-Centered Spirituality, an umbrella of traditions that includes Wicca, Paganism and Druidism. The large stones comprising the circle were removed from the side of the hill overlooking the Academy's visitor center, where erosion threatened to collapse them onto the visitor center. The circular nature in which the stones were placed lent itself to facilitating outdoor worship services.
Following the Earth-Centered community's request, the Academy spent approximately $80,000 to upgrade the area, adding flagstones to enhance the circle's safety and a fire pit to accommodate religious services. Cameras were added to protect the site from unauthorized access.
The Falcon Circle was dedicated in an official ceremony May 3, 2011, making it the newest of the Cadet Chapel's worship areas. It is open to use by all religious communities to worship in a manner respectful of other faiths; however, in the event of scheduling conflicts, the Earth-Centered community receives precedence."
£50,000 on a stone circle - but then the stones just happened to be there already.
