Teufelsberg logo proposal

Teufelsberg is a hill made with debris leftover from the Second World War. In addition to providing beautiful views of Berlin, the site is also home to an abandoned Cold War-era US listening post.
Now it’s a shabby reminder of the city’s history and an opportunity to combine sightseeing with stunning scenery.

Here a photo of the Teufelsberg complex: https://i.ytimg.com/vi/fnJgHsWoI98/maxresdefault.jpg

In German, Teufelsberg can be translated in "Devil's mountain": the two red triangles want to remember the Devil's horns.

Any comment, suggestion or advice is more than welcome.

Thank you!
