Very colourful, isn't it?
Well, looking at this photo, one things catches my eye more than anything else: the shadows the wall casts on the sidewalk. Call me weird, but I think they fit the scene very well, since this is a viewpoint above a beach... with waves... :)
If you lean a little over the wall, you can see the "Whale Beach" (Praia da Baleia). It got its name in 1872, when a huge whale got stranded there and it's only one of the many beautiful beaches you can find in Ericeira, which shores are very well know among surfers.
