I just found that Swastika flag was unfurled over Eiffel Tower in world war 2!! :o
Youtube videos mentioned it [Here] (https://www.youtube.com/watch?v=XxiVDQpU8H8) and [Here] (https://youtu.be/79p8KI-vg_Q?t=2879) .I could find Wikipedia mention with reference also.But couldn't find any clear image than [an interesting photo of a banner flying from the Arc de Triomphe, with the Eiffel Tower in the background] (http://forum.axishistory.com/download/file.php?id=127138) or [this] (http://www.agefotostock.com/age/en/Stock-Images/Rights-Managed/NOR-NP00053513) with google search . is there any better picture for proof??
This historical blog on the occupation of Paris during WWII has a clear picture of the Nazi flag flying above the Eiffel Tower.
The US Holocaust Museum also has a German newsreel showing video of occupation forces raising the Nazi flag above the Eiffel Tower (see 1 minute 12 second mark). https://www.ushmm.org/wlc/en/media_fi.php?MediaId=186
