Alentejan megalithic landscapes

Anta da Candeeira (Redondo)
backed by the serra d'Ossa.

Beautiful and curious dolmen, with seven uprights and a perfurated backstone.
Its likely that the "window" is not contemporary with the megalith, and is probably due to a monk's reutilization, in the Middle Ages.
The textures and sizes of the stones make this monument one of the most perfect and worth to visit in the Alentejo region.
I join some images of the entrance of the dolmen with the sun light projected on the backstone, both (on black and white) suggesting the shape of the "thing" (or the whale, according to Cassen and Vaquero, 2003).
