 As well as commemorating the National Eisteddfod, the Gorsedd Stones continue to provide an important ceremonial venue for the proclamation of future National Eisteddfodau which according to tradition must be completed one year and one day prior to its official opening.The ceremony is conducted by the Archdruid of the Gorsedd of Bards who formally announces the particulars of the proposed venue.During the proceedings the Archdruid stands upon the Logan Stone, facing him, to the east cardinal point, is the Stone of the Covenant where the Herald Bard stands, and behind this are the Portal Stones that are guarded by Eisteddfod officials.
