City of Ruins
Under the bombs, in the cellars, life resists
📱 1 to 10 phones · 1 team per phone · Independent codes
For 33 days, Caen was pounded by Allied bombing. 70% of the city was destroyed. But beneath William the Conqueror's château, in thousand-year-old cellars, hundreds of civilians survived.
A city sacrificed to be liberated
Caen was supposed to be taken on the evening of June 6, 1944. It took over a month of relentless bombing to liberate it. In the smoking rubble, a Caen resistance fighter attempts the impossible: guiding entire families to the cellars of the medieval château, the last shelter standing in a collapsing city. Every street crossed is a gamble against death.

« "We destroyed Caen to liberate it. It is the cruellest paradox of this war." »— — General Bernard Montgomery, July 1944
Thirty-three days under the bombs
On June 6, 1944, the Allied plan called for the capture of Caen within the first hours of D-Day. But German resistance was fierce. The 21st Panzer Division blocked the British advance at the city gates. Thus began a siege of over a month that would turn Caen into a field of ruins.
The bombing began on the evening of June 6. Waves of RAF bombers dropped thousands of tonnes of bombs on the city. The historic quarters — Saint-Pierre, Saint-Jean, le Vaugueux — were reduced to dust. Amid the chaos, civilians sought refuge. Many gathered in the cellars of William the Conqueror's château, built around 1060, whose three-metre-thick walls withstood the explosions.
On July 9, 1944, Canadian and British troops finally entered the left bank of Caen. The right bank would not be liberated until July 20, during Operation Goodwood. The city was unrecognisable: 70% of buildings were destroyed, entire neighbourhoods had vanished. But William's château held. And from its depths, those who had found refuge emerged into a city they no longer recognised.
