Cities all over the world have intrinsic similarities and iconic differences and many places in each have been somewhat abandoned.

This week for Flickr Friday we’re looking to see what beautiful ruins, abandoned buildings or urban decay remain in your city or somewhere you’ve visited. The theme is “Urban Exploration.” Be sure to tag your photo #Urbex and submit it to the Flickr Friday group pool. Wow us!

We’ll publish a selection of our favorites next week on the Flickr Blog.
