The US military courthouse in Fürth has long gone. It was the biggest outside the USA. Happy times of watching trials on the murder of taxi drivers etc. (They had a great basement theatre too, in which they used to put on musicals and plays).
British military court buildings in Germany are on the rise, however. Here’s a video of Baroness Scotland opening a new court building in Sennelager. You can also see a couple of judges in ill-fitting, perhaps borrowed, ceremonial wigs.
