On the Left Bank, across from the Cathedral Notre Dame, and a few steps down rue St. Jaques, is the Church of St. Severin, The Solitaire.
Its history begins in the 6th century when Clodald, the future Saint Cloud, escaped the massacres of his uncles Childebert and Clotaire in 524. Clodald built a monastery and became a disciple of the hermit Severin.
The oratory of the hermitage was destroyed by the Normans. A chaple was built in its place in the 11th century and it became the church of an immense parish, comprising nearly all of the southern part of Paris.
The oldest remaining parts of the Church of St. Severin are the bell-tower and the first three spans of the nave, dating from the 13th century. The rest of the church dates from the second-half of the 15th century.
