The history of this tower, on account of its close connection with the history of St. Patrick, cannot fail to be interesting. Caligula, or Caius Caesar, who died A.D. 41, meditated a descent upon Britain, and with that object marshalled his troops at Bononia. Fearful, however, of the dangers and fatigues of a long campaign in that inhospitable island, and full of childish vanity, he determined at length, as Suetonius humorously observes, "to make war in earnest; he drew up his army on the shore of the ocean, with his ballistse and other engines of war, and, while no one could imagine what he intended to do, on a sudden commanded them to gather up sea shells and fill their helmets and the folds of their dresses with them, calling them 'the spoils of the ocean due to the Capitol and the Palatium.' As a monument of his success, he raised a lofty tower, upon which, as at Pharos, he ordered lights to be burnt in the night time for the guidance of ships at sea" ("Lives of the Twelve Caesars," Caligula, p. 283). "It seems generally agreed," writes Forester, the translator of Suetonius' Lives, "that the point of the coast which was signalised by this ridiculous bravado of Caligula, somewhat redeemed by the erection of a high house, was Itium, afterwards called Gessoriacum and Bononia (Boulogne), a town belonging to the Gaulish tribe of the Morini" (note, p. 283). For many centuries this tower called Turris Ordens, Turris Ardens, or Turris Ordinis by the Romans, and Neamthur by the Gauls, spread its light over land and sea on the north-eastern cliffs of Boulogne.
