   Descend Into the City the Romans Never Knew Was Below Them

   history $

   Oppenheim sits on the Rhine trade route the Romans built — and directly above 40 kilometres of medieval tunnels that even the Romans didn't dig.

   📍 WHERE: Oppenheim Kellerlabyrinth entrance, Merianstrasse 2a, 55276 Oppenheim (town tourist information office; 49.8556°N, 8.3614°E).

   💡 WHAT: The Romans stationed troops along this Rhine bend, and Oppenheim existed as a crossing point on their frontier road. But the extraordinary thing beneath this town is purely medieval: 40 KILOMETRES of tunnels on up to five levels, carved into the loess between the 12th and 17th centuries. Oppenheim held a legal right called Stapelrecht — all merchants passing through had to stop and offer their goods for sale. Limited surface space on the Rhine bend meant everything went underground. What started as wine cellars became grain stores, refuge tunnels, the entire invisible infrastructure of a Rhine trade empire. The extent was so unknown that when the city commissioned a survey, investigators were still finding new passages. Smithsonian Magazine called it "one of Europe's most elaborate" underground systems — and the ONLY such system in Germany.

   🎯 HOW: Guided tours only; depart from the tourist information office. Tours run April–October, Wednesday–Sunday. Tour I: ~500 metres, 5 levels, about 1 hour. Tour II: 250 metres, narrower passageways. Book ahead: +49 6133 4909-19 or info@stadt-oppenheim.de. Cost: approximately €7–9 per adult. Before or after, walk up to the Katharinenkirche ruins on the hill (Merianstraße 6) — Gothic construction began in 1225, the same decade the tunnels were started. Standing in its roofless nave above a city that is mostly underground is genuinely strange.

   🔄 BACKUP: If tours are sold out, the Katharinenkirche exterior and ruins are always free and open. The churchyard view down the Rhine toward Nierstein shows you exactly why the Romans chose this bend for their frontier.

   Walk the Red Slope That Formed When Germany Sat at the Equator

   adventure Free

   The Roter Hang above Nierstein is the most distinctive terroir in all of Rheinhessen — iron-red clay formed 280 million years ago in a subtropical desert, now producing some of Germany's greatest Riesling.

   📍 WHERE: Start at Kilianskirche, Nierstein (49.8685°N, 8.3835°E). The trailhead is a 15-minute walk from Nierstein S-Bahn station — take the train from Mainz, 20 minutes.

   💡 WHAT: The red color under your feet is not rust or oxidation — it is 280-million-year-old iron from a desert that existed when this part of Germany drifted near the equator. The earth was compressed, buried, and eventually folded into the Rhine cliff where it now faces southeast toward the river, soaking up heat like a radiator. Roman soldiers stationed on the Rhine Limes looked at this red hillside from their boats. Today it grows some of the greatest Riesling in the world, and the 8-kilometre circular trail with 12 information stations lets you taste that context literally: multiple wineries along the route offer glasses at their cellar doors. The Brudersberg viewpoint was voted "Most Beautiful Wine View in Germany" in 2012 — on a clear day you can see Frankfurt's skyline to the northeast.

   🎯 HOW: The full loop takes approximately 2.5 hours at a wine-stopping pace. Audio guide and QR codes at the 12 red station boards explain the geology and history in English. Free to walk; wine by the glass at various points costs €4–8 per glass. Train-accessible year-round. Bring water — the exposed south-facing slope has no shade in summer.

   🔄 BACKUP: If weather is poor, simply drive the Rhine Terrace road (B9) north from Nierstein to Nackenheim — the red slope face is visible from the road and the view from roadside pullouts toward the Rhine is nearly as striking.

   Taste Riesling From the Red Slope at the Estate That Owns the Best of It

   wine $$

   Weingut Gunderloch sits at the foot of the Roter Hang in Nackenheim, where banker Carl Gunderloch bought the Rothenberg site in 1890 and the family has made some of Germany's most mineral Riesling ever since.

   📍 WHERE: Weingut Gunderloch, Carl-Gunderloch-Platz 1, 55299 Nackenheim (49.8870°N, 8.3310°E). On the Rhine bank, north end of the Roter Hang.

   💡 WHAT: The estate owns parcels in Hipping and Pettenthal (Nierstein) and the Rothenberg and sole-owned Fenchelberg sites in Nackenheim — the very heart of the red slope. Six generations of the same family have worked these vineyards since 1890. Their Rieslings taste like iron and citrus zest — the signature of 280 million years of compressed tropical-desert soil meeting cool German autumn. The Nackenheimer Rothenberg GG is one of the benchmark wines for understanding what Roter Hang Riesling actually means: the red mineral note is not a tasting note metaphor, you can genuinely smell and taste the ancient soil. When you ask them which vineyard parcel they're most proud of, expect a 20-minute answer.

   🎯 HOW: Contact the estate to arrange a visit and tasting: +49 6135 2341 or via gunderloch.de. They offer production area and cellar visits alongside premium tastings. A premium tasting with cellar tour runs approximately €25–40 per person depending on wines selected. The cellar is carved into the red slope itself — you taste the wines in the same geology that made them.

   🔄 BACKUP: If Gunderloch is fully booked, the WeinErlebnisWelt Heise tasting room in Nierstein (weinerlebniswelt-heise.de) is an accessible alternative with Roter Hang wines from multiple producers. Also: Weingut Lisa Bunn and Weingut Seck in Nierstein both welcome walk-in visitors.

   Find the 17-Hectare Walled Vineyard That Named a Billion Bad Bottles

   history Free

   In the city of Worms, surrounded by a stone wall, a single vineyard gave its name to Liebfraumilch — and then watched as that name was stretched to cover 10 million bottles of industrial bulk wine from across Germany. The original vineyard survived. It is now a VDP Grand Cru.

   📍 WHERE: Liebfrauenkirche, Liebfrauenstift 22, 67547 Worms (49.6318°N, 8.3590°E). The vineyard surrounds the church; approach from the north side for the best view of vines against the Gothic facade.

   💡 WHAT: In 1400, Kloster Liebfrauenstift monks began cultivating vines in the monastery gardens surrounding a Gothic church that took 198 years to complete (1267–1465). An English traveler mentioned the wine by name in 1687 — "Liebfraumilch," milk of Our Lady. Napoleon secularised the monasteries in 1808 and wine merchant Peter Joseph Valckenberg bought the vineyard at auction; the family still owns it, now in the 7th generation. The 17 hectares of Riesling inside the stone wall are today classified as VDP Grand Cru — one of Germany's most certified wine sites. Meanwhile, from 1910 onward, German wine law progressively allowed any wine from anywhere in Rheinhessen (and eventually the Pfalz and Nahe) to be labeled Liebfraumilch. By the 1970s, 10 million bottles of industrial semi-sweet wine bore the name. Jancis Robinson says the looser definition "almost managed to destroy the reputation of German wine and Riesling." The original vineyard, surrounded by its stone wall, never changed. It just watched.

   🎯 HOW: The vineyard exterior is visible from the street year-round and free. Standing between the vines and the church facade is one of wine's great contrast moments: 17 hectares of Grand Cru, city traffic on three sides, 600 years of monks and scandal. Church interior visits require advance appointment: +49 6241 44267. The estate wine (Weingut Liebfrauenstift / Valckenberg) can be purchased in Worms wine shops.

   🔄 BACKUP: If you can't reach Worms, the story travels — the nearby Nibelungen Museum in Worms (Burgundenstrasse 10) gives the cultural context of Worms as an ancient city, and the cathedral (Wormser Dom) is one of the great Romanesque buildings on the Rhine.

   Stand at the Gate of the Most Impossible Riesling in Germany

   Optional

   wine $$$$

   Klaus Peter Keller makes perhaps 400 bottles a year of G-Max — named for his great-grandfather Georg and youngest son Max — from a secret parcel of old-vine Riesling on limestone. The average retail price is over $2,000. Almost none of it is ever for sale. The estate itself, in a quiet village in southern Rheinhessen, looks nothing like a legend.

   📍 WHERE: Weingut Keller, Bahnhofstraße 1, 67592 Flörsheim-Dalsheim (49.6980°N, 8.2090°E). A village in the Wonnegau area, about 45 minutes south of Mainz by car.

   💡 WHAT: Klaus Peter Keller took over winemaking in 2001 — the same year he made the first G-Max "for personal consumption." The wine comes from a single parcel of very old Riesling vines, planted on limestone with cuttings his mother Hedwig sourced from ancient Saar vines at a nursery decades before. The exact location of the parcel is a Keller family secret. Almost the entire production is sold as part of the "Kellerkiste" — a case of 6 bottles (5 Grosses Gewächs Rieslings + 1 G-Max), priced around $1,500 from the estate. On the secondary market: $4,000+. There are six double magnums of the 2009 in existence. The 2023 vintage was described as "a tension that one must have experienced oneself to believe it — and then one still does not believe it." This is Rheinhessen, the region everyone dismissed for 30 years as Germany's bulk wine heartland.

   🎯 HOW: Visits require advance contact by email or phone — this is not a drop-in winery. Email: [email protected]. Phone: +49 6243 456. Website: keller-wein.de. Request a vintage presentation or tasting of aged wines — these are offered to serious visitors. The standard tasting of GG Rieslings (not G-Max) runs approximately €40–80 per person. If you are invited to taste a G-Max, you are one of very few people who will do so in a given year. Even if you can't visit, the village itself — Flörsheim-Dalsheim, population ~4,000, completely unremarkable on the surface — represents the entire arc of Rheinhessen's transformation. This is where Germany's greatest wine is made, in a region everyone abandoned.

   🔄 BACKUP: If Keller cannot accommodate a visit, Weingut Wittmann in Westhofen (Weinstraße 52, 67593 Westhofen; wittmannweine.de) is the region's other undisputed benchmark — biodynamic since 2004, four VDP Grand Cru sites, Philipp Wittmann has been making world-class dry Riesling since 2003. The drive between Dalsheim and Westhofen takes 15 minutes; doing both in one day is entirely possible.
