It's impossible to make a huge review about these Tumulus. There are a lot in Djibouti. I'm not sure if these should be inscribed. I think not. But there are many near Lake Abbeh as well, which, maybe, could be inscribed together with the lake as a cultural landscape. They are, as stated, a pile of black rocks mainly. They are not like other "beautiful" tumulus in other parts of the world. Nothing really special.
