Saint Louis Cathedral at a Glance

About Saint Louis Cathedral

Saint Louis Cathedral (Cathédrale Saint-Louis de Carthage) is a former Roman Catholic cathedral located on Byrsa Hill in Carthage, Tunis Governorate, Tunisia. It was constructed in the late 19th century during the French protectorate.

The building is notable for its prominent position overlooking the Gulf of Tunis and for being part of the Carthage historic ensemble visited together with Roman and Punic remains. The exterior and hilltop setting are the main draw; the site is frequently photographed for its views over the sea and adjacent archaeological park.

The cathedral was built under French colonial administration in the late 1800s and named for Louis IX of France. After Tunisian independence the church was secularized and repurposed for cultural uses.

The cathedral stands on Byrsa Hill within the modern suburb of Carthage, overlooking the Gulf of Tunis and adjacent to the archaeological park and national museum; it lies within the greater Tunis metropolitan area.

  • Proximity to Carthage ruins: Sits on Byrsa Hill immediately beside the Carthage archaeological site and the Carthage National Museum, making it easy to visit both the ruins and the former cathedral in one trip.
  • Current use: After Tunisian independence the building was secularized and has been used for cultural events and exhibitions since the 1960s.

Getting There & Around

How to Get to Saint Louis Cathedral

The Cathedral of Saint Louis in the Carthage area (Tunis Governorate) is reachable by the coastal TGM light-rail line (Tunis-La Goulette-La Marsa). Take the TGM from Tunis Marine toward La Marsa and alight at Carthage/Byrsa station, then walk a few minutes to the cathedral and archaeological area. By car it is a short drive northeast from central Tunis along the coastal road (approx. 10-20 km depending on start point).

Tips for Visiting Saint Louis Cathedral

  • Visit early in the day to avoid the midday heat and to get the best sea light from the cathedral terrace over the Gulf of Tunis.
  • Approach the site from Byrsa Hill/Carthage archaeological area and combine the stop with the nearby Carthage National Museum and ruins for full context rather than treating the cathedral as an isolated ruin.
  • Take the short walk up to the cathedral terrace and viewpoints-the panoramic views over the coast are often overlooked by visitors who linger only in the ruin itself.
