View of an inflatable and accessable bubble made of transparent plastic below the towers befoer the official opening on the Willy Brandt square in Frankfurt/Main, Germany, 7 September 2017. The bubble was set up as a so-called 'Pop Up Monument' by the Jewish Museum. It is said to reflect the temporary and fragile character of Jewish places and contrast the skyline of Frankfurt with its fragile skin. In addition to a small exhibition, lectures, movie screenings, concerts and discussions will take place here until 11 September.
