Twilight by John W. Campbell:
Science Fiction Inventions, Technology and Ideas

"A story that will set you to dreaming of purple distances—of a far future world wherein a race is dying seven million years away—seven million years!"

"And all the great city-structure throbbing and humming to the steady, gentle beat of perfect, deathless machines built more than three million years before—and never touched since that time by human hands. And they go on. The dead city."


('Twilight' by Don Stuart (John W. Campbell).)

Interesting "tale of a stranger" kind of story; this story was originally published under Campbell's pseudonym of Don A. Stuart.
