Reperi was an ancient Roman Town of Roman North Africa, in the Roman province of Mauritania Cesariense. The exact location of the ancient town is now unknown, but is surmised to have been in Northern Algeria. The town seems to have last till the Muslim conquest of the Maghreb. Using only the above description and what you know about the world, "Nobody knows where exactly Reperi was located in Roman North Africa." is definitely correct, incorrect, or inconclusive?
