Ruined buildings

I just love the way buildings that had been destroyed to ruins look. Whether from a catastrophic event or just the course of time, seeing one fills me with awe at the beauty of nature re-absorbing what had once been theirs.

Great grey concrete monoliths utilizing the whole of what we have developed over thousands of years. Inexpensive buildings built fast and with massive scale. Hundreds of people had walked in and out of their doors, going about their lives, and yet now they're empty. What else was left in these buildings, determined to be worthless as well?

Buildings expected to be sturdy crushed to rubble, solid walls that fell from water, ceilings that stretch far into the sky, and yet fall to quakes - nature conquering all.
