Austro-Hungarian military graves in Sighisoara

In the graveyard on top of the hill of Sighisoara/Schassburg citadel

Looks very nice, like in a ... gothic movie.

I notice that alot of the graves were from 1917! The front was not at Sighisoara in 1917? Could it be that the these soldiers died at the front in Moldova and were buried in Sighisoara?
Also there is a grave visisble with date killed of 1915. Romania was not at war with AH in 1915. Could it be that that was a soldiers killed on the Russian fron and buried in Sighisoara because he was from there?

With regards a date of death being in 1915,

the soldier could have been in service on the Western Front,

fighting against France / Belgium.

fighting against Serbia,

fighting against Italy,

or in Poland, or on the Eastern Front.

as well as the Russian Front.

If he was in service in any of those theaters, why would they have transported the body back to Sighisoara? Only reason I could think is that the soldier was from there.

This is correct. The graves are of local people that have died during the First World War in various theaters of war. Note that the most of the names are German, not Hungarian, as the town was of German ethnicity.

The ethnic distribution of the deceased burried in a certain cemetery depends largely on the cemetery's religious denomination, i.e. one can probably find very few Germans burried say in the Orthodox cemetery of the city.
