The German Fountain (Turkish: Alman Çeşmesi) is a gazebo styled fountain in the northern end of old hippodrome (Sultanahmet Square), across from the Mausoleum of Sultan Ahmed I. It was constructed to commemorate the second anniversary of German Emperor Wilhelm II's visit to Istanbul in 1898. It was built in Germany, then transported piece by piece and assembled in its current site in 1900. The neo-Byzantine style fountain's octagonal dome has eight marble columns, and dome's interior is covered with golden mosaics.
