This week’s Flickr #TBT theme is #Cities.

Most urban landscapes are in constant change. Do you remember how your city or your neighborhood looked like years ago? We’d love to see it! Share the Flickr URL of your photo in the comment section of our Facebook post or in our Twitter Feed (@Flickr #TBT #Cities), and we’ll show the best ones next week on the Flickr Blog.

And get to know Flickr Commons! This view of the city of Stockholm in 1945 is from the Swedish National Heritage Board.
