The most mighty building I’ve seen must be the Köln Dom (and I have seen the great wall and the heart of Linn). A huge, enormous catholic church in the center of Köln, Germany. I went there many times during my days at Photokina and the outside was as powerful as the music was on the inside. I will go to bed now but before doing so I wanna show you this image. Please enjoy the full resolution version as well.
Short history, first stone were laid in the 13th century. Work stopped 1520 at 57m height because of no money. Work continued 1842 and was finished 1880 at 157m height. (if I remember correctly)
Lens: Sigma 30mm. Camera: Sigma SD10. Good night.
