Paris attack survivors await start of France’s biggest ever criminal trial

20 men accused of involvement in 2015 massacre, but it is unclear whether the key accused will break their silence

Deep inside Paris's historic law courts on the bank of the River Seine, builders were putting the finishing touches to an extraordinary architectural structure described as a cross between a high-security bunker and modern church.

Its sleek pale wood and white lighting were chosen by the French justice ministry to create a sense of calm" in contrast to the horrific events which will soon be examined there. This temporary structure will from next week host the biggest criminal trial ever held in France, when 20 men are accused of planning, aiding and carrying out the November 2015 Paris terrorist attacks on a stadium, bars and restaurants and the Bataclan concert hall.
