At the Seville Cathedral, Seville, Spain.
This cathedral has multiple entrances, and the one we (all tourists, really) went through was the Door of the Prince. While I stood just outside the entrance, I looked up and clicked a quick few shots. I turned those photos into a monochrome HDR, but kept the upper part slightly blurred to emphasize the height of the structure. Some split-toning brought out the contrast between the higher, brightly lit sections and the lower, shaded parts.
For themed Monochrome Madness: Straight.
