...getting deeper...


The ancient city of Syene (today known as أسوان ''Aswān'' or Assouan) is located due south of Alexandria at a distance of 5000 Greek stades.

In Syene there is a very deep well. Every year at noon on the day of the summer solstice (21 June) the sunlight illuminates the water at the bottom of this well. At that moment, the sun is directly overhead and there are no shadows in the city of Syene.
