Roman emperors once inhabited this 2,000-year-old town - and left their mark, in a diversity of styles which form the town's unique character.
The Roman amphitheatre, the imperial thermal baths and Constantine's basilica all contribute to the town's distinctive ancient appearance.
Trier Cathedral, Germany's oldest episcopal church, is a further attraction popular with visitors. Next to the neighbouring Church of Our Lady, Roman, Salian, Romanesque-Gothic and baroque architechture fuses together to form an expressive ensemble of churches depicting Germany through the ages.
Trier is also home to the Römerbrücke bridge, the Barbarathermen thermal baths and of course the town's most famous landmark, the 1,800-year-old Porta Nigra gate, which has recently been restored. The town has been a UNESCO-World Heritage site since 1986.
