Heidelberg Castle is a world-renowned sandstone ruin overlooking the Neckar Valley, combining elements of Gothic and Renaissance architecture. The structure occupies a hillside position above the Heidelberg Old Town, having been expanded by various Electors Palatine over several centuries. It suffered major damage during the Nine Years' War in the late 17th century and from subsequent lightning strikes. Today, the complex includes the Ottheinrich Building, a prominent example of German Renaissance design, and the Great Vat cellar. The castle courtyard hosts regular cultural events, including the Heidelberg Castle Festival. Visitors can access the grounds and explore the palace remains, while the Pharmacy Museum is located within the complex. It remains one of the most significant architectural legacies of the Palatinate region.
