it's a part of an stone arc, belonging to a historical Atash-kade ( today Zoroastrian Temple ) near persepolis, named "Firooz Abad Atash-kade "
plz judge this one aestatically seriously.
the whole of the monument is built of stone & gypse, no bricks at all.

As you can see I went in even closer as I wanted to cut out part of an arch on the left and wall on the right that is not as clearly defined as one on the left. I reset the white and black points and also tried to rescue some detail from the overexposed sunlit part. Any good?
