A Few Hours in Trier: Germany’s Oldest City

When planning our Europe trip, Trier honestly wasn’t supposed to be anything more than a quick stop between countries. But after exploring Luxembourg City, we realized Germany’s oldest city was only about 45 minutes away… and there was no way we were passing that up.

So after wrapping up our Luxembourg adventure (which you can read all about in our 24 Hours in Luxembourg guide), we crossed the border into Germany for a few hours in Trier - and immediately wondered why this place isn’t all over everyone’s Europe itinerary.

Because somehow this city has:

massive Roman ruins
colorful storybook streets
giant cathedral squares
palace gardens
and some of the oldest architecture in Germany

…yet barely anyone talks about it.

📍Porta Nigra

Our first stop was the city’s most famous landmark: Porta Nigra (€6 per adult).

Pictures do not prepare you for how massive this thing is.

Built by the Romans around 170 AD, Porta Nigra is one of the best-preserved Roman gates in the world and somehow still standing nearly 2,000 years later. Trier’s Roman history is honestly wild, and this was the moment it really hit us just how ancient this city actually is.

📍Hauptmarkt

Next up was the gorgeous Hauptmarkt, Trier’s historic market square. This area instantly gave us those classic European vibes we’re constantly chasing - colorful buildings, outdoor cafés, cobblestone streets, and enough charming corners to completely destroy your camera roll storage.

It’s one of those places where you don’t really need an itinerary. Just wander, grab a coffee, and soak it all in.

📍Trier Cathedral & Church of Our Lady

One thing we loved about Trier is how compact and walkable everything is. Within just a few minutes, you can go from Roman ruins to cathedrals to palace gardens.

The Trier Cathedral is another must-see and is actually the oldest cathedral in Germany. Even if you’re not normally someone who visits churches while traveling, this one is worth stepping inside.

Right next door, make sure to also check out the beautiful Church of Our Lady, one of the oldest Gothic churches in Germany and a completely different architectural style from the cathedral beside it.

The entire square around the cathedral also just feels incredibly grand and historic.

📍The Pink Electoral Palace

Right nearby, you’ll find the stunning Electoral Palace, which genuinely looked like something straight out of a Wes Anderson movie.

The soft pink exterior, manicured gardens, and elegant architecture made this one of our favorite photo spots in Trier. If you visit in spring or summer, we can only imagine how beautiful the gardens would be in full bloom.

📍Trier’s Roman Baths

Before leaving the city, we explored the Kaiserthermen, also known as the Imperial Roman Baths (€6 per adult).

Walking through the underground tunnels and ancient ruins here was honestly one of the coolest parts of our visit. Trier really feels like one giant open-air history museum… except somehow way less crowded than places with half the history.

Is Trier Worth Visiting?

Absolutely.

If you’re already visiting Luxembourg, the Rhine Valley, or western Germany, Trier is such an easy addition to your itinerary. It’s affordable, incredibly photogenic, packed with history, and perfect for travelers who love discovering places that still feel a little underrated.

And for us, Trier ended up being the perfect introduction to the Germany leg of our Europe trip.
