Saint Louis Cathedral (French: La cathédrale Saint-Louis de Carthage) is an old Roman Catholic cathedral located in Carthage, Tunisia.Situated on the peak of Byrsa Hill and near the ruins of the ancient Punic and then Roman city, the cathedral was built on the ruins of the ancient temple to the punic god of healings Eshmun, that can still be accessed from the basements.Since 1993 the cathedral is known as the "Acropolium" and is no longer used for worship but hosts events or concerts of Tunisian music and classical music.
