In the 16th century, Louis V helped place Heidelberg Castle at the epicenter of science and learning. First by writing a famous book of medicine, then by expanding the castle?s library to house more books.

From toads swimming in the grounds' fountains to peregrine falcons nesting in the bell tower, tour a medieval mausoleum steeped in nature.
