Heidelberg, A Fairytale Town

A Day Trip to Heidelberg

On 11 December, we booked a guided day trip to Heidelberg, gathering at the meeting point on Wiesenhüttenplatz in Frankfurt for a 9:30am start. The drive south took under an hour, but it felt like stepping into a different century — Heidelberg was barely touched by the bombing that flattened so many German cities in the Second World War, so what we were about to walk through was the real, unbroken thing: a university town that's looked more or less like this since the 1700s. Our guide, a friendly elderly gentleman who'd clearly walked these streets a thousand times, made the history feel personal rather than recited.

Up to the Castle

We climbed toward Heidelberg Castle, its red sandstone ruins perched on the wooded slope of the Königstuhl above the town. The castle was never quite finished, and it's never really been whole since — building work stretched across four centuries as one Elector Palatine after another added a new wing, and then a run of disasters undid most of it: lightning strikes in 1537 and again in 1764, and French troops who blew up entire sections during the Nine Years' War in the 1690s. Standing at the old stone gate tower, flanked by two carved knights holding lions on shields, it was easy to imagine just how much this crossing once mattered — this was the only way in.

Inside the walls, the Ottheinrichsbau stopped us in our tracks. It's considered one of the earliest and finest examples of German Renaissance architecture, its facade covered floor to roof in carved statues and ornament — and yet it's been a roofless ruin since the French destroyed it in 1693, its windows open straight to the sky. There's something quietly moving about a building that grand left permanently unfinished, restored just enough to stay standing rather than pretending to be whole again.

In the cellar below, we found what the castle is arguably most famous for: the Großes Fass, the Great Heidelberg Tun, an enormous oak wine barrel built in 1751 that can hold around 220,000 litres — big enough that a dance floor was later built on top of it. Legend has it the castle's court jester, a man named Perkeo, was famous for outdrinking everyone who challenged him, and supposedly died after being persuaded to drink a glass of water for once. Our guide told it completely deadpan, and it was the kind of odd, specific detail that stuck with us long after the architecture blurred together.

Down into the Old Town

From the castle terrace, the view opened out across the Neckar River, the Old Bridge, and the pastel rooftops of the old town below — the same view that reportedly moved Mark Twain to write about Heidelberg in A Tramp Abroad after he stayed here in 1878. We made our way down into that view, following Hauptstraße, the town's long pedestrian spine, with the onion-domed tower of the Heiliggeistkirche — the Church of the Holy Spirit — rising ahead of us over the market square.

The market square itself was strung with a small Christmas market — string lights, mulled wine, and wooden stalls set up right at the foot of the church, with the castle ruins still visible on the hillside behind the rooftops. Heidelberg has also been a university town since 1386, the oldest in Germany, and that student-city energy still runs through it — cafés, bookshops, and bicycles everywhere you look, layered over all the history.

Look up as you wander the old town and you'll spot small carved figures tucked into the corners of buildings — Baroque-era house shrines, often a gilded Madonna and child sheltered under a stone scallop shell, a leftover habit from when this was solidly Catholic territory. We nearly walked straight past one, high above a shopfront, before someone in our group pointed it out — one of those details that's easy to miss and hard to un-see once you know to look for it.

The Old Bridge

We then crossed the Karl Theodor Brücke, better known as the Old Bridge, a stone crossing first completed in this form in 1788. Halfway across, we stopped and looked back — the castle above, the church tower behind us, the river below — and understood immediately why this exact view has been painted and photographed for so long. The bridge has its own guardian too, a stone bridge gate with twin towers that once controlled who came in and out of the city. Back up in the castle courtyard earlier that morning, the Friedrichsbau had given us the same feeling in reverse — rows of Palatine rulers carved into their own niches, watching over the grounds instead of the river.

A Simple Afternoon

With the guided part of the tour finished, we had a little time left to explore on our own — pretzels, coffee, and a quick stop at a souvenir shop, plus a slower walk through corners of the old town the tour hadn't covered. By late afternoon, we returned to Frankfurt, carrying with us the quiet charm of Heidelberg — a town that survived the century that flattened everything around it, and still wears its scars, from a blown-open Renaissance facade to a jester's legendary last drink, without ever losing its warmth.
