Gothic architecture was revolutionary in the 12th century because it allowed for very tall structures with relatively thin walls. And thin walls meant plenty of windows and lots of light. Compared to previous styles, Gothic architecture was light and airy but to inhabitants of the 21st century, these places are dark.
And the darkness makes this photo what it is, since the main lighting is the soft light reflecting up into the faces of the two men attending to the votive candles. In the medieval mindset, light warded off evil, so even a single candle made a dark place safer and more holy.

Pink is perhaps a more accurate color to describe this amazing structure. The color comes from the unique, local sandstone from which it is constructed. This cathedral is the 7th tallest church in the world and for 2 1/2 centuries it was the tallest building in the world. The cathedral's namesake town sounds German and the food looks German, but trust me - it is in the beautiful Alsace-Lorraine region of eastern France. On a side note, terrorists sought to detonate a bomb in the square in front of the cathedral in 2000 but the plot was revealed and foiled.
