Heidelberg is one of those places that immediately justifies every superlative — a city of extraordinary depth where Germany’s oldest university, a dramatically ruined Renaissance castle, a storied medieval bridge, and a beautifully preserved Baroque old town all come together along the banks of the Neckar River. We arrived from Rüdesheim by continuing upriver on the Rhine to the Main River, docking in Frankfurt before taking a bus south to Heidelberg. Sandy and I had read about this city for years, and it exceeded everything we anticipated — the castle alone would justify the detour, but Heidelberg keeps delivering at every turn. First mentioned in 1196 with origins reaching back to Roman and Celtic settlements, the city’s medieval foundation is centered around the iconic Heidelberg Castle and the Church of the Holy Spirit, while centuries of academic life and Romantic-era poetry have layered it with a richness few German cities can match.
Heidelberg University
One of Heidelberg’s most distinguished claims to fame is its university, founded in 1386 by Rupert I, Elector Palatine. Heidelberg University is Germany’s oldest and one of Europe’s most prestigious institutions, renowned for its research and intellectual heritage. Over the centuries, it has been home to influential scholars and thinkers, including those who shaped Renaissance humanism and the Protestant Reformation. The university’s reputation for academic excellence continues today, with cutting-edge research clusters and a vibrant international student body.
The university’s history includes darker chapters as well. Hans Himmel defended his doctoral thesis at this Heidelberg University building. He was a Nazi Party member and SA affiliate who held high academic and administrative positions at the university during the Nazi era, playing a key role in the university’s Nazification and the exclusion of Jewish scholars and others deemed enemies of the regime. The SA was a violent paramilitary wing of the Nazi Party responsible for street-level intimidation and political violence, and Himmel’s membership placed him within an organization integral to the Nazi seizure and consolidation of power.
Martin Luther did not attend Heidelberg University, but he did participate in the Heidelberg Disputation of 1518 — an early theological debate where Luther expanded and clarified his ideas, particularly on salvation by grace through faith and the bondage of the will. The Lutheran Church as an institution had not yet formed at the time, but the Heidelberg Disputation proved pivotal in spreading Reformation theology throughout Europe.
Heidelberg Castle
Heidelberg Castle is one of Germany’s most iconic landmarks — a sprawling, partly ruined Renaissance palace perched on a red sandstone hill 80 meters above the Neckar River valley. The castle is best reached by the Bergbahn funicular railway from Kornmarkt in the old town, and the views from the Great Terrace over the city and river below are nothing short of spectacular. Sandy and I spent a good part of our afternoon here, and even with limited time the castle rewards every moment you give it.
The castle’s history dates back to the early 13th century, with the first structures built before 1214 by the Counts Palatine of the Rhine, who later became prince-electors of the Holy Roman Empire. Over the following centuries it was expanded, destroyed, rebuilt, and expanded again — its current form reflects multiple architectural phases spanning Gothic, Renaissance, and early Baroque styles. Much of what visitors see today dates to the 16th and early 17th centuries, with the dramatic ruins a result of French destruction during the War of the Palatinate Succession in 1689 and 1693, followed by a series of lightning strikes.
The castle is as famous for its legends as its history. Inside the Great Cellar stands the enormous Heidelberg Tun — one of the world’s largest wine barrels, built in 1751 and capable of holding approximately 219,000 liters. A dance floor was once constructed on top of it, and the court jester Perkeo served as its devoted guardian.
One of the castle’s most beloved legends involves Perkeo, the royal court jester known for his legendary capacity to drink wine. According to the story, Perkeo was the devoted guardian of the Heidelberg Tun, drinking vast quantities daily without apparent effect. His undoing came when he accidentally drank water — which, the legend says, led to his death. Perkeo remains a beloved mascot of Heidelberg, his wooden effigy still standing watch beside the great barrel.
Another castle legend concerns the iron ring door knocker on the residential courtyard entrance. According to the tale, whoever could bite through the ring would inherit the castle. A witch attempted the feat and managed to sink her teeth into the iron, but failed to bite it completely through — leaving a mysterious mark that visitors can still see today.
Visitors to the castle are often intrigued by a foot imprint found on the Great Terrace. The origin remains unexplained and has become part of the castle’s mythology. One theory holds that it belonged to a lover who leapt from a window after being caught with the ruler’s wife — and landed, inexplicably, on his feet.
Walking Around Heidelberg
Heidelberg’s architectural charm is a blend of medieval and Baroque styles. The city was largely rebuilt in the Baroque style after suffering destruction during the War of the Palatinate Succession in the late 17th century, yet it retained its medieval street layout. The result is an old town that feels both grand and intimate — wide Baroque facades lining streets laid out in the Middle Ages, with the castle looming over everything from the hill above. The main Hauptstraße pedestrian zone runs the full length of the old town, connecting the market square, university buildings, the Church of the Holy Spirit, and the Old Bridge in one easy, flat stroll.
The city played a significant role in German intellectual and political history. It was a center for Romanticism, attracting poets and philosophers like Friedrich Hölderlin and Clemens Brentano, who contributed to Heidelberg’s enduring nickname as the “City of Romanticism.” In the 19th and 20th centuries, Heidelberg became a beacon of liberal thought and scientific progress, and after World War II it served as headquarters for the US Army in Europe — one of the few major German cities to survive the war largely intact.
The bronze monkey sculpture at the Old Bridge is one of Heidelberg’s most beloved landmarks. Known as the Heidelberg Bridge Monkey or Brückenafe, its history dates back to the 15th century. The original was a stone statue placed on the tower of the Old Bridge, serving as a symbol of mockery and a reminder to passersby to reflect on themselves critically. The monkey famously showed its bare backside toward Mainz across the river, symbolizing defiance against the Bishops of Mainz and their lack of power over the Electors of the Palatinate.
The original statue was destroyed during the Nine Years’ War in the late 17th century. In 1979, sculptor Gernot Rumpf created the current bronze version at the Old Bridge. Unlike the original, this monkey shows the “horned hand” gesture meant to ward off the evil eye, and holds a mirror in one paw symbolizing vanity and self-reflection. Small bronze mice accompany the statue as part of the sculptor’s signature. The statue is steeped in local symbolism: the naked rear represents shamelessness; the mirror and ring symbolize vanity; and the hand gesture is a protective sign. Local tradition holds that rubbing the mirror brings wealth, touching the monkey’s fingers ensures a return to Heidelberg, and stroking the mice brings fertility and good fortune for children.
We finished the afternoon at an outdoor cafe with pretzel-crust pizza and a couple of glasses of Riesling — watching Heidelberg life go by along the river. It’s that kind of city: you can spend hours absorbed in 600 years of history, then step into a sunny cafe and feel perfectly at home. Today Heidelberg is a dynamic, youthful place — roughly 40% of its population is under 30, drawn by the university and a cluster of research institutions and colleges. With its picturesque Neckar River setting, extraordinary historic sites, and vibrant academic energy, Heidelberg is one of the great cities of Germany and not to be missed.

The Heidelberg Bridge Monkey (Brückenafe) is a famous bronze sculpture at the entrance to the Old Bridge over the Neckar River, created by sculptor Gernot Rumpf in 1979 to replace a 15th-century original destroyed during the Nine Years’ War. The monkey holds a mirror symbolizing vanity and self-reflection. Local tradition holds that rubbing the mirror brings wealth, touching the monkey’s fingers ensures a return to Heidelberg, and stroking the bronze mice at its feet brings fertility and good fortune.
How old is Heidelberg University?
Heidelberg University was founded in 1386 by Rupert I, Elector Palatine, making it Germany’s oldest university and one of the oldest in the world still in continuous operation. It has shaped Renaissance humanism, the Protestant Reformation, and modern science over its 600-plus-year history, and remains one of Europe’s leading research institutions today.
How do you get to Heidelberg from Frankfurt?
Heidelberg is approximately 80 kilometers south of Frankfurt and easily reached by train (about 1 hour from Frankfurt Hauptbahnhof), by bus, or by car via the A5 autobahn (45–60 minutes). We arrived by shore excursion bus from Frankfurt during our Uniworld Rhine river cruise, having docked on the Main River. Heidelberg makes an excellent day trip from Frankfurt or a natural stop on any Rhine Valley itinerary.

A half-day allows time for the castle, the Bridge Monkey, and a stroll along the Hauptstraße — which is how we experienced it on our cruise shore excursion. A full day lets you explore at a more relaxed pace, including the university area, the Church of the Holy Spirit, and a walk along the Philosopher’s Path on the opposite bank of the Neckar, plus a proper lunch or dinner in the old town.
Practical Tips for Visiting Heidelberg
Take the Bergbahn funicular up to Heidelberg Castle rather than walking — it’s included in the castle admission price and saves your energy for exploring the grounds themselves. The views from the Great Terrace over the Neckar valley and old town are spectacular and deserve time to be savored.
Don’t miss the Heidelberg Tun wine barrel inside the castle’s Great Cellar. Even if wine isn’t your primary interest, the sheer scale of it — 219,000 liters, with a dance floor once built on top — is genuinely impressive, and the legend of Perkeo the jester makes it one of the more entertaining stops in any German castle.
Make time for the Bridge Monkey at the Old Bridge. It takes only a few minutes, but the symbolism and the tradition of touching the mirror, fingers, and mice make it one of Heidelberg’s most memorable and photogenic stops. Go earlier in the day to avoid the biggest crowds.
The old town’s Hauptstraße pedestrian zone is flat and very walkable — a single stroll connects all the major sights without backtracking. Start at the Old Bridge, walk west along Hauptstraße past the university and the market square, and end at Kornmarkt for the funicular up to the castle.
If you’re arriving on a river cruise shore excursion, the bus from Frankfurt takes 45–60 minutes each way. Plan your time at the castle carefully to allow a comfortable return without rushing.
Spring is a beautiful time to visit. The castle gardens were in full bloom when we were there — irises, lilacs, and chestnut blossoms everywhere. The combination of flowering gardens and dramatic castle ruins made for some of the best photography of our entire cruise.
