These are some of the community kitchen cob ovens at the
Festival in Portugal.
The festival has won several awards for using natural building
and permaculture principals that ensure they leave no trace on the
earth. If you would like to build a cob oven, Ziggy has written a
cob oven guide which shows you how to build your own oven for
around $20. If you would like more design inspiration take a look at the
cob oven collection on the Natural Homes Facebook page.
