Heidelberg Castle is one of Germany’s most iconic Renaissance ruins, perched above the Neckar River since construction began in the 13th century. Its dramatic mix of intact wings and weathered ruins — the result of wars, fires, and a lightning strike — made it a symbol of the Romantic movement in the 19th century.
Highlights include the ornately carved Ottheinrichsbau facade, the Great Barrel (the world’s largest wine cask), the German Pharmacy Museum, and the Great Terrace, which offers sweeping views over Heidelberg’s old town.
Most visitors spend about two hours exploring the castle grounds and museums, or roughly 90 minutes if focused only on the main highlights. A funicular railway connects the castle to the old town below.
