Editing Stone circle (section)

===Africa===
Ancient stone circles are found throughout the [[Horn of Africa]]. [[Booco]] in northeastern [[Somalia]] contains a number of such old structures. Small stone circles here surround two enclosed platform monuments, which are set together. The circles of stone are believed to mark associated graves.<ref name="Tpficss">{{cite book |author=Hussein Mohamed Adam |editor=Charles Lee Geshekter |title=The Proceedings of the First International Congress of Somali Studies – Somali Studies International Association |date=1992 |publisher=Scholars Press |isbn=0891306587 |pages=37, 40 |url=https://books.google.com/books?id=mM8tAQAAIAAJ|access-date=9 November 2014}}</ref>

At [[Emba Derho]] in the [[Ethiopian highlands|Ethiopian]] and [[Eritrean highlands]], two kinds of megalithic circles are found. The first type consists of single stone circles, whereas the second type comprises an inner circle enclosed within a larger circle (i.e. double stone circles).<ref name="Verlag">{{cite book |last1=Institut für Afrikanistik und Aẗhiopistik – Universität Hamburg |title=Aethiopica: International Journal of Ethiopian Studies |volume=7-8 |date=2004 |publisher=Harrassowitz Verlag |page=27 |url=https://books.google.com/books?id=0_svAQAAIAAJ |access-date=1 January 2015}}</ref>

The [[Senegambian stone circles]] are found on the western side of the continent. The individual groups are dated from 700 A.D. to 1350 A.D, and 1145 sites were mapped in a 1982 study.<ref name="Curdy"/>
