The Romanesque cruciform church of Saint Mary in Zahna with its massive tower was built in 978. Fläming immigrants rebuilt the church in the 12th century so that it is now considered the oldest church in the Fläming region. The flanking aisles and church towers were destroyed in the 15th century and never rebuilt, giving the church a rather squat and bulky appearance. The last ruler of Zahna, the Provincial Governor of Saxony and Knight Albrecht of Leipzig is said to have been buried in the church. The faithful probably stopped here on their way from Wittenberg to Jüterbog to see the seller of indulgences Johann Tetzel.
