The unique medieval round houses of the Alentejo

Near Marvão and Castelo de Vide hidden away in some small sleepy Alentejo villages you can find these unique medieval stone round houses called "choças".
These circular buildings are from the iron age, more than two thousand years old. They are made with dry stone walls and conical roofs made out of broom.
You can find several of these in the villages of Barretos and Cabeçudos and in the last century some families still lived in them.
Most of them are now used as storage or are in a ruined state and have been abandoned.
These unique buildings should be restored and kept as part of Marvão and Alto Alentejo heritage.
