Dietrich's pilgrimage can be dated to between 1171 and 1173, during the reign of King Amalric of Jerusalem, when the Holy Places were under Christian control. It began in Acre during March or April. From there he took the road to Jerusalem, Jericho and the river Jordan. He went back by the same route and was in Acre preparing to embark on the Wednesday of Easter Week. He may have made a detour to visit Nazareth, Tiberias and Mount Tabor, but his description of the Sea of Galilee is very confused. His description of the Church of the Holy Sepulchre indicates that he was there during the renovations financed by the Emperor Manuel I Komnenos. He is also the earliest source to mention the Sultan's Pool, then a newly constructed cistern.
