Erfurt Cathedral

Erfurt Cathedral, also known as St Mary's Cathedral, is the largest and oldest church building in the Thuringian city of Erfurt, central Germany. It is the episcopal seat of the Roman Catholic Diocese of Erfurt. The cathedral was mainly built in the International Gothic style and is located on a hillside overlooking the main town square, directly next to St Severus' Church. As a unique architectural ensemble, both churches together form the city's landmark. Former German names include Marienkirche and Propsteikirche Beatae Mariae Virginis.
