The Basilica of Saint-Cyprien is identified as the church built over the tomb of Cyprian, the third-century bishop of Carthage who was martyred during the Decian persecution and remains one of the most important figures in early Latin Christianity. The basilica was constructed in the fifth century and rebuilt in the sixth, then destroyed during the Arab conquest.
What survives today is the foundation plan and a substantial fragment of one of the apsidal walls, set in an open archaeological park on the northeastern edge of ancient Carthage. The mosaic floor of the central nave is partially preserved and includes the bishop's name in Latin inscription. The site is rarely visited but easy to find — and the views down to the sea from the bluff above the basilica are one of the best in this part of the city.
