The head of the Maronite church leads mass on Holy Thursday inside Lebanon’s most notorious prison every year.

Twelve Christian inmates are selected from Roumieh Prison’s general population to receive communion. Maronite Patriach Bechara Rai washes their feet as Jesus Christ did for his disciples, described in the Gospel of John.

Roumieh Prison is situated in the mountains just north of Beirut. The facility is overcrowded, and falls short of the UN’s minimum standards for prisons. A cell block that houses members of ISIS and other extremist groups is off-limits to prison officials.
