I was impressed with all the good answers last time, so here's another one with the same theme. I was fortunate enough to be able to take these pictures of a famous German WW2 radar antenna rotting in a field not far from where I live. This classic radar system was first put into use by the Luftwaffe in about 1940, and was considered very advanced for its time. Like the last quiz, the name begins with a W.....Good luck!

Answer: Würzburg, or however you want to spell it.
