Trier is Germany's oldest, or one of the oldest cities. Trier was founded by the Celts as Treuorum 4BC and 300 years later it was conquered by the Romans and changed name Augusta Treverorum. The historical core is partly well preserved with several historical buildings intact, such as the romanesque, roman catholic Trier Cathedral (Hohe Domkirche St. Peter zu Trier) that is the oldest church in Germany (completed 1270 but the foundations was buit by Romans in the 4th century), the gothic twin Liebfrauenkirche (Church of Our Lady) that is connceted to the cathedral and St Gangolf Kirche (baroque/gothic from 1344) at Hauptmarkt, that also feature many other beautiful buildings. Especially baroque and half-timbered houses can be found at Hauptmarkt, where large soap bubbles where made for kids, and many people attended open air restaurants.

Simeonstrasse leads to Porta Nigra (Black Gate), an impressive large dark gate built by the Romans. Aula Palatina (Konstantinbasilika), Electoral Palace (Kurf├╝rstliches Palais) and Roter Turm (Red Tower) are impressive historical buildings situated around Willy-Brandt-Platz and Konstantinplatz. At the square Kornmarkt you find the pink baroque building Posthof, the French Casino and the beautiful fountain/sculpture Sankt Georgsbrunnen. Opposite the cathedral is the square Domfreihof and the Palais Walderdorff, a pink and white baroque palace. Many sights are UNESCO sites. Theodor-Heus-Allee is a mighty boulevard that leads to Hauptbahnhof, the Central station that 1878 but has a modernist main building today. Beneath the station the green hills that surrounds Trier can be seen.
