Romantic Ruins Above the Neckar
Heidelberg Castle has dominated the hillside above the city for over seven centuries, evolving from a simple medieval fortification into a magnificent Renaissance palace complex before being devastated by French troops in 1693 and struck by lightning in 1764, leaving the picturesque ruins that have inspired artists and writers ever since. The castle's partially ruined state is itself a major part of its appeal, as the crumbling red sandstone walls overgrown with ivy create an atmosphere of melancholy beauty that made it a pilgrimage site for Romantic-era poets, painters, and philosophers including Goethe and Mark Twain. Twain wrote in A Tramp Abroad that 'a ruin must be rightly situated to be effective' and declared Heidelberg Castle the finest he had ever seen, a judgment that most visitors continue to endorse. The castle complex encompasses buildings from the Gothic, Renaissance, and early Baroque periods, creating an architectural timeline that spans four centuries of German palatial design.
The Grosses Fass and Castle Interior
The castle's most famous curiosity is the Grosses Fass, or Great Barrel, an enormous wine vat built in 1751 that holds 221,726 liters and is the largest wine barrel in the world, testament to the Palatinate Electors' legendary enthusiasm for wine. Legend attributes the barrel's guardianship to Perkeo, an Italian dwarf court jester who allegedly drank nothing but wine from this barrel and dropped dead the single time he was persuaded to drink a glass of water instead. The Ottheinrichsbau facade, built between 1556 and 1559, is one of the earliest and finest examples of Renaissance architecture north of the Alps, with elaborately sculpted figures representing biblical, mythological, and planetary subjects. The German Pharmacy Museum, housed within the castle, contains a fascinating collection of historical pharmaceutical equipment, medicines, and laboratory instruments spanning five centuries of medical history.
Views and the Old Town
The castle terrace and gardens offer magnificent panoramic views over Heidelberg's red-roofed old town, the arching span of the Old Bridge, the winding Neckar River, and the Rhine plain stretching toward the horizon. The Hortus Palatinus, the castle's terraced Renaissance garden once celebrated as the eighth wonder of the world, survives in partial form and provides a peaceful setting for contemplation and photography. The castle is reached either by a scenic ten-minute walk up the steep Burgweg from the old town or by the Heidelberg funicular railway, which continues further uphill to the Konigstuhl summit at 568 meters for even more expansive views. The illumination of the castle on summer evenings, particularly during the three annual castle illumination festivals when fireworks and red Bengal lights create a spectacular display, is one of the most photographed scenes in Germany.
