Lost Rivers ~ Rediscovering Urban Waterways!

Thanks to Jason King at LandscapeUrbanism for spotting the trailer for Lost Rivers documentary by Caroline Bâcle and Katarina Soukup...

"Once upon a time, in almost every city, many rivers flowed. Why did they disappear? How? And could we see them again? This documentary tries to find answers by meeting visionary urban thinkers, activists and artists from around the world."
