The gates and walls of ancient Nicea. They were already 600 years old at the time of the first ever ecumenical council (decides god is a trinity) and nearly 1,000 years old for the seventh (icons are cool, but not to be worshiped). A further 1,200 years and our footsteps are kicking up some of the same dust. I can’t help it. I found it cool. Best ruins ever. (These walls are functional, not decorative. They used anything for building materials, including hunks of columns scavenged elsewhere.)
