Der Kathedral St Sebastian by Mariajoy
There were several lovely churches in the city centre which we didn't have time to investigate unfortunately. St Sebastian's was one of them!
St Sebastian's is also considered to be a cathedral. The cornerstone was laid in 1015 by archbishop Gero. IIt was destroyed in the same city fire as the other churches and buildings in Magdeburg, and then re-built as a gothic church in the 14th/15th century.
