The cathedral of the Thuringian state capital, the Erfurt Market Church of St. Mary, is located on the city’s central cathedral square and is built in the late Romanesque style. As early as 725, Boniface built a church on the Domberg, which is now considered the predecessor of Erfurt Cathedral. Its construction began in 1154. Particularly remarkable is the High Choir, a 15-metre-high single-nave high Gothic hall built on three basement levels with its magnificent Baroque altar. Pupils and teachers of the Erfurt Cathedral School sat here during services in the mid-14th century. The impressive Gothic windows are well preserved. The “Gloriosa” bell is known worldwide.
