Roman ruins travel guides

Passau's headline sights cluster around the cathedral, but the city rewards anyone willing to cross a bridge or climb a hill. This guide covers the Mariahilf pilgrimage church and its 321-step covered stairway, the Inn-side promenade past Schaiblingsturm, the Veste Oberhaus complex and its museum, and the Roman Museum Kastell Boiotro, with notes on free grounds versus ticketed interiors and limited-mobility access.

Baden-Baden is famous for its thermal baths, but a quieter side rewards slow wandering: two contrasting gardens, the free Lichtentaler Allee and Kurpark, the Trinkhalle colonnade, Roman bath ruins entered through a tunnel under Friedrichsbad, and the free Hohenbaden castle ruins on the hill.

Trier's Porta Nigra is free to admire from the street, but the gate passage and upper galleries are ticketed. This guide separates the two, sets out 2026 admission and seasonal hours, flags the scaffolding, and explains the separate centurion tour and the AntikenCard Trier.

Trier compresses Roman gates, a medieval market square, two churches and several bath complexes into a compact old town. This suggested one-day route starts at Porta Nigra, pauses at the Hauptmarkt wine stand, pairs the Cathedral with Liebfrauenkirche, and ends at one Roman bath site.

Cologne is more than its cathedral. This guide points to bone chapels, above-ground Roman remains, medieval gates, specialist museums, and neighborhood corners such as the Belgian Quarter and Ehrenfeld, plus practical notes on checking access before you commit a day to any one stop.
