There is this Unite for Heritage photo contest run by @unesco. All you need to do is post photos of sites, places, objects, and cultural traditions that matter to you as cultural heritage and tag them with #Unite4Heritage. You can post as many photos as you wish, but you only need to make sure that you also include an inspiring story about why cultural heritage is important to you. The contest is open until 18 August, 2015 and you can go to their page for more details.

About the photo above: The remains and the ruins of the #Persepolis (515 BC), central #Iran, were declared by #UNESCO as a World Heritage in 1979. | iPhone 5s

I think the cultural heritage from the past is a part of our identity today belonging to all nations regardless of time and geography no matter where they are located or who has created them.
