Within the majestic walls of the famous castle for which Heidelberg is renowned, lies a true treasure for curious travelers — the German Pharmacy Museum. It is one of the world's most extensive and detailed exhibitions dedicated to the evolution of pharmacy, from the alchemy experiments of the Middle Ages to modern scientific discoveries. Germany is rightfully proud of this museum, which occupies several historical buildings of the castle complex, including the elegant Otto Henry Palace.

The exhibition is spread across eleven halls, where visitors can see authentic interiors of historical pharmacies from the Renaissance, Baroque, and Biedermeier eras. On display are rare collections of pharmaceutical vessels made of fragile faience and delicate glass, as well as antique instruments ranging from heavy mortars and scales to early microscopes. The museum impresses with its atmosphere of mystery, recalling times when medicine bordered on art.
Of particular value is the extensive library and archive, which houses ancient recipe books and decrees that regulated the work of pharmacists hundreds of years ago. Thanks to the harmonious combination of the castle's ancient architecture and carefully designed displays, the museum attracts hundreds of thousands of tourists from around the world every year, all eager to glimpse behind the scenes of medical practice from centuries past.
