This is the famous Unite d'habitation of Marseille.
The roof terrace that you see, is both a hanging garden
and a belvedere and it provides a gymnasium, outdoor
theater, nursery school, paddling pool etc. This roof is
for the dwellers a space of public appearance and is
set against the backdrop of distant mountains, evoking
the agoras of the antique world.
Warm regards to all of you.
