"

The memorial's foundation stone was laid on April 2, 1914 by Minister of War Enver Pasha.[2] Its construction lasted two years and it was inaugurated in 1916.[3] Designed by the renowned Turkish architect Vedat Tek, the conical columnar monument features a broken top made of white marble. The broken top symbolizes the flight mission's incomplete status. A branch of laurel made of bronze is fixed on the lower half of the column. The monument is about 7.50 m (24.6 ft) high.[3] A large bronze medallion is attached on each of the two opposite sides of the marble base on which the column stands. On one medallion are inscribed the names and the officer ranks of the victims. On the other are depicted a monoplane, the Beyazıt Tower and the landscape of Istanbul is the form of a relief.[1]
