Archaeological remains dating from the 5th century were unearthed at the site of rescue excavations under the current Martyrs Square which will host the future Museum- subway station of Algiers. The polychrome mosaic floors of a functional basilica until the end of the fifth century are presented now on the excavations to which Minister of Culture Khalida Toumi and the governor of Algiers Abdelkader Zoukh paid an inspection visit.
