Before there was Germany, there was Trier: Augusta Treverorum, founded in 16 BC and at times the residence of Roman emperors. The Porta Nigra, the imperial baths, and the Constantine Basilica still stand — all UNESCO World Heritage.
What to See
- Porta Nigra: the best-preserved Roman city gate north of the Alps.
- Imperial baths & amphitheatre: bathing culture and gladiators — walkable ruins.
- Cathedral of St. Peter: Germany's oldest bishop's church, home of the Holy Robe.
- Hauptmarkt: one of the country's most beautiful market squares.
- Karl Marx House: birthplace of the city's most famous son.
In Trier, "old town" is meant literally — 2,000 years, not 500.
Getting There and the Tour
Trier lies about 2 hours west of Frankfurt Airport, idyllically on the Moselle. The private Trier day trip (from €480) gives you 4–5 hours on site; Moselle-loop photo stops fit nicely on the way back.
Combine with Luxembourg
Luxembourg City is only 50 km further — many guests combine the two via the Luxembourg day trip with a Trier stop. More under day trips from Frankfurt.
