Loropéni is located in Burkina Faso

Loropéni is a market town in southern Burkina Faso, lying west of Gaoua. Local features include ancient stone ruins, about which little is known. One theory is that they formed the enclosure of the courtyard of a Kaan Iya (king or paramount ruler of the Kaan people) from antiquity. The ruin is called "kpóŋ kayaŋga" in the Kaansa language, meaning "the rejected fortress," based on a Kaan legend that the fortress was abandoned after a Kaan Iya died shortly after moving the royal courtyard into the fortress. There is a similar, though much-degraded ruin around the current royal courtyard in Obiré.
