Pope Fabian
A certain Müller, a burgher of Berlin, endowed a chapel in gratitude for his lucky rescue from a Saracen assault during his pilgrimage to Jerusalem. On 18 October 1484 Arnold von Burgsdorff, Prince-Bishop of Brandenburg, issued an indulgence, promising all those helping to restore the chapel 40 days less in the purgatory. The indulgence is the oldest surviving document mentioning the chapel, then consecrated to Mary(am) of Nazareth, the Holy Cross, Pope Fabian, and Sebastianus of Narbonne. The chapel was then located in the fields about 1 km outside of "St. Gertrud's Gate" (close to today's Gertraudenbrücke) of the city of Cölln (a part of today's borough Mitte of Berlin) on the highway to Magdeburg and Leipzig (today's Axel-Springer-Straße and Lindenstraße).
