Today, I have visited two community gardens, one located in Badalona (Spain) and the other located in Sant Adrià del Besòs (Spain).Both they use the farmland of old cottages. Now the cottages are public buildings.
Can Cabanyes in Badalona
Can Serra in Sant Adrià del Besòs.
It is a way to preserve the agriculture, the landscape and the public space, while the retired people cultivate their vegetables.
