Trier, Rheinland-Pfalz- remnants of the past in Trier give an almost continuous account of European history. Among the traces of Roman civilization are a bridge across the River Mosel, three bathing establisishments, the basilica, an amphitheater and the Posta Niagra, a massive city gate. Medieval buildings still surviving include the Romanesque cathedral, the Basilica of St. Matthias and the baroque St. Paulinuskirche.
In addition to the wealth of preserved architecture, Trier is capital of the Mosel region, and as such a center of the wine trade. Visitors arrive annually for the August wine festival.
