The Basilica of Tebessa is one of the most extensive monuments in the city of Tebessa. It is originally a basilica and a Christian church that was called the Church of Saint Crispin. It is located 460 m north of the Byzantine citadel. It is surrounded by a four-sided wall. It consists of several buildings that collectively form a monastery and internal catacombs And stables, corridors, courtyard, church and its facilities, and the chapels of shrines. Today, due to the passage of time, nothing remains of the church except the remains of archaeological stones and external gardens, and some columns that have remained standing.
