The German Fountain is a gazebo styled fountain in the northern end of ancient Roman-Byzantine hippodrome, Sultanahmet Square, Istanbul, Turkey. It was constructed to commemorate German Emperor Wilhelm'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.
