This monolith belongs to the Vigeland installation in Oslo's Frogner Park, an impressive series of sculptures by Gustav Vigeland, who also was the designer of the Nobel Peace Prize medal. I had a rather clear memory of the sculpture's intricate designs, but when I rediscovered this image, what struck me was the way the vertical gray mass is carved into the deep blue of the sky.
