Before each day's sitting of the House of Lords, the Lord Speaker forms part of a procession that marches from the Lord Speaker's residence to the Lords Chamber. The Lord Speaker is preceded by the Deputy Serjeant-at-Arms or Principal Doorkeeper of the House (who bears the Mace). The procession is joined by the Gentleman Usher of the Black Rod in the Prince's Chamber. Together, they move through the Not-content Lobby, entering the Chamber below the bar, and finish by walking up the Temporal (opposition) side toward the Woolsack. The Mace is placed on the Woolsack, where the Lord Speaker sits after a bishop has led the House in prayers.
