Lahneck Castle

Lahneck Castle (Burg Lahneck) in Lahnstein sits on a rocky spur above the point where the Lahn river meets the Rhine, and forms part of the UNESCO Upper Middle Rhine Valley World Heritage Site. With its rare pentagonal keep and neo-Gothic interiors, it is one of the lesser-known castles of the Rhine. If you are looking for a Rhine castle without the crowds, this is a good choice.

Where it is and how to get there

Lahnstein lies on the Rhine just south of Koblenz in Rhineland-Palatinate, roughly 1.5 hours by car from Frankfurt. The castle stands above the district of Oberlahnstein at Burgweg 1. The walk from town is uphill; the castle's website does not give parking details, so ask before you go. For trains and buses use the Deutsche Bahn journey planner.

Why it is worth a visit

Archbishop Siegfried III of Mainz began building the castle in 1226. It was first called Logenecke and renamed Lahneck after 1365. In 1400 the electors met here and deposed King Wenceslaus. French troops burned the roofs in 1688, and the castle was later rebuilt in neo-Gothic style. In 1907 a naval officer, Robert Mischke, bought the property, and his family still owns it. The keep is about 29 m (95 ft) tall and pentagonal, a shape rare in castle building. Goethe wrote a poem here in 1774.

What to see

• The keep and castle chapel: both are the main sights inside the walls.
• Interiors: furnished rooms with paintings and furniture, usually seen on a guided tour.
• The view: you look across Lahnstein and the Rhine to Stolzenfels Castle on the opposite bank.
• Legends: the story of Idilia Dubb, a tourist said to have died in the tower in 1851, and a tale about the Knights Templar. Neither is historically confirmed.

Tickets and opening hours (as of October 2026)

According to the Romantic Rhine tourism portal, the castle is open from 7 April to 1 November 2026, Tuesday to Sunday, 11 a.m. to 3 p.m. It is closed on Mondays except Easter Monday and Whit Monday. Admission is 12 euros for adults and 6 euros for children up to 14. We could not check these details on the castle's own website, so confirm by phone or email before you travel.

Tips for visitors

Plan about 1.5 to 2 hours. The castle is on a steep hill, and we found no accessibility information, so call ahead if you need step-free access. The castle is also known for the "Rhine in Flames" fireworks events.
