Baptistère Saint-Jean (Baptistery of St. John) is a religious edifice in Poitiers. It is reputed to be the oldest existing Christian building in the West and one of the most prominent examples of Merovingian architecture. The baptistery currently holds a small museum which includes many stone sarcophagi dating from the fifth to seventh centuries, many of which are vividly decorated with carved designs. It also includes remnants such as pieces of Roman columns, baptismal fonts, and other stone relics.
Church of St. Radegund (French: Radegonde) is a medieval Roman Catholic church, dating from the 6th century. It takes its name from the Frankish queen and nun, Radegund, who was buried in the church. Considered a saint, the church became a place of pilgrimage by those devoted to her heavenly intercession. The current church, constructed from the 11th to 12th centuries, was built in a combination of Romanesque and Angevin Gothic architectural styles.
