With 11 churches, including its stately cathedral, the Roman city of Trier presents a magnificent opportunity for Catholic pilgrims. The Cathedral and its Bishop's museum, with a collection of archaeological finds and Christian art, stand on top of a former Constantinian palace right in the heart of the city. The Church of Our Lady, built in the 13th century, is the oldest Gothic church in Germany, while the Basilika, Constantine's throne room, is the largest surviving single-room structure from Roman times.
