I believe that this was the tower for Deutschlandradio Kultur at Zehlendorf near Oranienburg Germany on 177 kc.

It sure looks taller than 36m as some have described it.

Its sure does.

Wikipedia lists the configuration at one time being an "Omnidirectional aerial, cage aerial mounted on 359.7 m high guyed mast, triangle aerial on 3 150 m high guyed steel lattice masts".  The transmitter was this 500kW Continental transmitter.

I hope the TX can be/is put in a museum properly! Those are works of art.

My uncle in The Netherlands used to listen to a classical music station on LW. I forget which one, but it was fascinating to me how those stations carried -forever- it seemed. Also very cool was the abundance of multiband AM, FM, LW, SW receivers in homes and cars (MW, KW, LW, SW there). Those Phillips and Grundigs... the sound, the sound...

About 15 years ago in Romania, I installed a new matching network for their 153 khz longwave transmitter.  I think it was at a town called Bod.  My rental Land Rover had a standard car radio in it with longwave band included.  I was able to listen to the station even over on the western border in Timisoara, under a spider web of electric trolley wires.  The story was that the Romanian government maintained that station partly so that its sailors in the Black Sea could have access to Romanian programming. 
I can't recall the power, but it was plenty.  We installed a new ground radial screen for the two-tower array, and it seemed that the tractor with the ground laying plow would almost be out of sight  before snipping the wire and coming back for another run.  It might have been a 400 kw transmitter, but I'm not sure.
There were at least two other European LW stations that I could hear reliably anywhere in Romania.  Longwave, with sufficient power, penetrates day or night.

One of my faves was Atlantic 252 (500,000W d / 100,000W n) which was marketed as an alternative for Radio Luxembourg 208 (1440AM - 1,200,000W) when the latter wasn't airing their U.K. targeted programming at night.

Atlantic 252 had a fun contemporary hit format. LOVED those stations!

How about those xmtr powers? Makes the 50kW stations here look wimpy.
