@movq@www.uninformativ.de Thanks, mate!
This funnel is a famous landmark originally built in the 40ies or 50ies on top of a hill range by a local coffee roaster modeled after their logo for advertising purposes. They were called “Schwäbische Kaffeewerke” or something like that. As a coffee guy, you might have heard of them. :-)
When this company went bankrupt several decades later, a chemistry plant nearby expanded to that site and flattened most of the infrastructure, but took over the funnel. They maintain it now. You can see some of their larger office highrises on the right. Luckily, most of their buildings, tanks, chimneys, etc. are on the opposite hill side and in the valley, so they’re out sight from this point of view and don’t further ruin the shot.
A few years ago, they underwent a rebranding and – at least surprisingly to me – changed their logo to also incorporate said funnel now. Giant ads lives forever, I reckon.
