Formal event surrounding the Hamidiye Mosque and palace in Yildiz

A large crowd is gathered around the palace and Hamidiye Mosque in Yildiz in Istanbul, Turkey. In the left-hand corner of the photograph, many carriages are parked with men and women standing among the carriages. In front of the carriages are many, many soldiers on horseback in review lines facing away from the camera. This photograph hints that this was a very large and formal occasion which may have included a military review. Printed in handwritten white ink in the bottom corners of the photograph, "N. 226. Yildiz Kiosque. G. Berggren SS."
