Trier Cathedral (Trierer Dom) is the oldest church in Germany and serves as the cathedral for the Roman Catholic Diocese of Trier. Its core structure dates back to a 4th-century Roman double church, with significant expansions occurring in the 11th century to create the fortress-like appearance seen today. It is a UNESCO World Heritage site as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier.
