The church and abbey of St Savin sur Gartempe.
According to tradition, in the 5th century two brothers, Savin and Cyprien, fled to escape being killed for their Christian beliefs. They were caught and beheaded near this site. Around the year 800 their relics were found and a church dedicated to shelter these relics was founded. The church exterior is fairly plain. The spire was added in the 14th century.
Once inside you can see the amazing 11th and 12th century paintings on the ceiling and walls. The columns are intended to look like marble.
Ceiling of the nave.The paintings on the ceiling depict various scenes from the Bible, chosen carefully to be suitable for the variety of people below who sat in different sections of the nave: monks, postulant monks, general public.
Needless to say, this treasure is protected. The site is on UNESCO's list of World Heritage Sites.
