Cool, Carlos
Well, at least it's fun to play. I don't drown in the Mediterranean or I am buried in a Sahara dune, lol. Using the data displayed by yourDNAportal EU K36 to obtain the geografic coordinates the center of my circle is in the western Mediterranean, city of Tadjena, Algeria. It is a beautiful and very green place located at Tell Atlas (Arabic: الاطلس التلي) that is a mountain chain over 1,500 km (932 mi) in length, belonging to the Atlas mountain ranges in North Africa, stretching from Morocco, through Algeria to Tunisia. As I said, the center of my circle is Tadjena, Algeria and, and within a radius of 400 km from this the center of the circle are Palma, Valencia, Alicante, Elche, Murcia and Almeria, in Spain, Oujda, in Morocco, in addition to Oran, Algiers and Setif in Algeria.
