The 2017 Germany 2 euro commemorative coin honours the federal state of Rhineland-Palatinate, featuring the iconic Porta Nigra in Trier as its central motif. As a UNESCO World Heritage site, this Roman city gate stands as a monumental testament to the ancient history of the region and the architectural prowess of the Roman Empire in Germania. The design captures the intricate stonework of the structure, which has served as a landmark for nearly two millennia. By selecting this site for the Bundesländer series, Germany highlights the historical significance of Trier, once known as Augusta Treverorum, and its enduring role in the cultural heritage of the nation. This coin was issued in 2017 with a mintage of 6,300,000 pieces.
