On 15 July 1524 Prince-Elector Joachim I Nestor and his entourage fled to the top of the Kreuzberg (then called Runder Berg), the highest of the Tempelhofer Berge, in order to survive a flood predicted for that day by his court astronomer Johann Carion. After spending much of the day on the Kreuzberg in vain, at about 16:00 h, Electress Elizabeth of Denmark urged her husband to leave. They returned to town, where a thunderstorm started and a lightning killed four horses and the coachmen. According to another source the news of their frightful flight had spread among the Cöllners and Berliners, many of whom had tried to get as well onto the Kreuzberg, but were kept out by electoral guards. On their return the crowd awaited the elector and his entourage and welcoming him laughing.
