In October 2018 I traveled to Germany for a history tour of World War II ruins, bunkers, extant buildings, et cetera.  This was a small group tour arranged by Harry Cooper of Sharkhunters International.  Before and after the tour I wandered around München, known as Munich to English speakers.  The 1972 Olympic Park is quite recognisable, but you may not immediately recognise the film locations from Willy Wonka and the Chocolate Factory (1971).

If you are interested in history told first person by a boots-on-the-ground researcher and by those who were part of it, look up Sharkhunters International.
