Isosceles in Lisbon

The Vasco da Gama Tower in Lisbon is a lovely sail shaped building overlooking the Tagus river.

This view is from the rear of the building looking straight up what I imagine to be the emergency staircase. Though I shot this scene in portrait orientation in an attempt to fit more in, it didn’t quite work in the frame, so resulted to using this landscape orientation instead. It certainly feels less restricted to me due to the negative space shown around the structure.
