Ukrainian soldiers are sent to The Forest Glade – Ukraine’s first centre for the treatment of psychological trauma – before returning to the frontline. After spending over three years in Russian captivity following the battle for Mariupol, 25-year-old Kyrylo Chuvak spends three weeks at the centre, a brief opportunity for rehabilitation. Hidden in the pines near Kyiv, this modest building offers soldiers psychological therapy as well as tango, archery, guided breathing, medieval games and quiet conversations over tea. After four years of war, and with waning international attention, the battle is not only taking place on the frontline but in the mind

A former Soviet military facility offers an unlikely respite – before its patients return, too quickly, to the frontline

Imagine a place hidden deep in a pine forest, with small lakes and ponies. Far from the noisy city. In the middle of it there is a modernist Soviet building with marble walls. Walls that have heard so many stories of suffering, loss and death.

This place was built in 1974 as a secret sanatorium for the ministers of Soviet Ukraine. Later it hosted soldiers returning from the 1979-89 Afghan-Soviet war. Then, from 2014, those coming back from the war in eastern Ukraine. And now, soldiers from every part of the Ukrainian front.
