The German Fountain (Turkish: Alman Çesmesi) is a gazebo styled fountain in the northern end of old hippodrome (Sultanahmet Square), Istanbul, Turkey
and 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 octagonal fountain stands on a base with eight steps rising up to an entry gate.
There are seven brass fountain spouts over basins on the remaining sides, and over the central reservoir there is a dome supported by eight porphyry columns.
The fountain's central reservoir stands on a mosaic-tiled platform and surmounted with the bronze dome, which is raised on carved marble arches.
There are eight monograms in the arch stonework and they represent the political union of Abdülhamid II and Wilhelm II.
In four of these medallions, Abdülhamid II's tughra is written on green background, and in other four Wilhelm's symbol "W" is written on a Prussian blue background.
Also, over "W" there is a crown and below it a "II" is written.
The fountain was surrounded with a bronze fence, but unfortunately this has been lost.
The outside of the dome is ornately patterned bronze; the dome's ceiling is decorated with golden mosaics and again with Abdülhamid II's tughra and Wilhelm II's symbol.
