More than 500 people from 30 different nationalities have found a refuge in a derelict housing complex of 228 apartments - 55 sq.m. each - in downtown Athens in what is probably the largest residential squat in Europe. Homeless, refugees, ex-addicts, ex-convicts and political activists have created an unlikely community where everyone is welcome and all issues are resolved in solidarity - from hijacking electricity from the urban grid to resolving personal conflicts. Today, when COVID-19 is exposing inequalities of the past, this unexpected neighboorhood teach us why communities matter.
