The tragic story behind this small, sacred monument—which, with its unusual color scheme, is sure to arouse interest and perhaps even entice passing bikers to stop for a moment—has already been described by user 'Jürgen' in his post. "These wayside crosses were erected as visible signs and attract the attention of many people. The cross is a symbol of life. It stands as a sign of our Christian hope and aims to direct our gaze to Jesus Christ, who has conquered death," as Dean Rainald M. Ollig once put it in the foreword to a publication about wayside crosses.
