Dur yolcu!

"Dur Yolcu" memorial,
Gallipoli, Turkey

Carved on a hillside on the Gallipoli peninsula, facing the town of Çanakkale, are these words:

Dur yolcu
Bilmeden gelip bastığın
Bu toprak
Bir devrin battığı yerdir.

Which translate (I believe) as something like this:

Stop, traveller!
This ground you tread
Unawares
Is where an era ended.

The Gallipoli Campaign was an imperial bloodbath that cost the lives of hundreds of thousands of men.

The beginning of the end of several empires: British, French, Russian, German, Ottoman.
