Big circles near Samarra iraq

[gcinam]

Check 34,13,05 N and 43,53,15 E

This is Samarra in Iraq. You will see some broken circular patterns.
compare them with following WW1 picture at http://www.mcah.columbia.edu/dbcourses/islamic/large/samarra_3.jpg
and these broken circles are much clearer. This can be a good bet for archeologists. I expect them to be some ancinet garden or palace.

please note that around 850 AD, Samarra was capital of one of biggest empires in history,streched from chinese Turkestan to Morocco.

Three courses for horse-racing were built east of the main city. Two have an out-and-back course 80m wide and 10.42 km long with a spectators pavilion at the start, and the fourth a pattern of four circles around a central pavilion (5.3 km).
