Schloss Heidelberg, the Heidelberg castle, and the old bridge is there in front of all of the boats. 

We took a boat cruise for the castle illumination. Three times during the summer, they reenact the burning of the castle from the last time the French came through and destroyed it in the 1600s. Behind us you can see the castle on the other side of the river. 

Off the the right of the big flame you can see the castle "burning". 

Fireworks! 

Ooooooh
