Heidelberg castle is illuminated at night on three evenings throughout the summer.
The last chance to witness this spectacle is Saturday at 10:15 p.m. when, once again, the castle will be illuminated in tones of red in remembrance of how French troops burned it in the late 1600s.
As the lights upon the castle fade, the sky over the Neckar River comes alive with fireworks. Find more at www.tinyurl.com/3p9ut7c.
