This is another photo that I think is impressive enough that it stands alone without too much talk.
It was taken in Flisvos, along the Athens seafront. I remember going for a walk along there one day, partly because it's always a nice walk, partly because some sort of art festival was on and I wanted to see the exhibits. One of the exhibits was this big construction that looked like an abandoned spaceship. There was a plaque with a description, but I can't remember what it said.
The spaceship itself looked like a concrete egg on three legs with a staircase into it. The photo as taken on the inside looking out the window towards the sea.
