 The "Stolperstein" is then inserted at flush level into the roadway or sidewalk, at the individual's last known place of freely chosen residence or work, with the intention to "trip up the passer-by" and draw attention to the memorial.The costs of "Stolpersteine" are covered by individual donations, local public fund raising, contemporary witnesses, school classes, or community funds.From the beginning of the project until 2012, one "Stolperstein" cost €95.
