Which was built first, the Theodosius Cistern or the German Fountain?
German Fountain The German Fountain (Turkish: "Alman Çeşmesi" German: "Deutscher Brunnen" ) 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 fountain's octagonal dome has eight marble columns, and dome's interior is covered with golden mosaics.
Altımermer Altımermer is a quarter located in the European part of Istanbul, Turkey. It is located in the western part of the district of Fatih (the walled city). Although it is difficult to define exactly its boundary, Altımermer lies between the neighborhoods ("mahalleler") of "Kocamustafapaşa" and "Seyyid Ömer". The main axis of the quarter, "Altımermer Caddesi", stretches between the neighborhoods of "Kocamustafapaşa" and "Sayyidina Umar". The name of the quarter, "six marbles" in English, comes from the broken fragments of a fallen Byzantine column which during the Ottoman period were supposed to have magic properties. In this quarter was built between the 5th and the 6th century the Cistern of Mocius, the largest water reservoir in Constantinople, known since the Ottoman period as the "Altımermer Çukurbostanı" ("the sunken garden of Altımermer", since it was used as vegetable garden), and now turned into the education park of Fatih.
