This #TwitterTuesday was about the concrete jungle. We asked you to show us the most beautiful #Buildings you had in your archives, and we got exactly what we asked for! You showed us, day and night, how stunning the urban scenarios can be, whether they are surrounded by water or by the city.

As always, thanks to everyone who submitted a photo! We highly recommend checking out all contributions in the @flickr Twitter feed.

To see the next challenge delivered directly to your feed, follow us on Twitter or on Flickr. We’ll be back on Friday with the week-long #FlickrFriday challenge and on Tuesday with the new #TwitterTuesday theme.
