A nation in the midst of the Great War, the people of the United States turned to prayer for victory, erecting an Angelus Prayer Siren in Washington, D.C.
On June 10th of 1918, clergymen, laymen, and city officials held a committee in the District Building of Washington, D.C., which houses the offices of the mayor and and council, discussing whether or not to have inaugurate an official Angelus noon prayer citywide.
That committee later voted to erect an Angelus prayer siren on the roof top of the now-demolished Evans building that went off everyday at noon to remind citizens to have a “minute of prayer for victory.”
The siren read:
“At 12 pray. Pause a minute every day at noon, and pray for victory, for our nation and our allies, for a peace enduring. Get behind our government.”
