The limestone is a fine grained oolitic limestone formed in shallow water lagoons in the Bathonian Age about 167 million years ago. The stone is homogeneous, and therefore suitable for carving.
Use in Building
The stone was first used for building in the Gallo-Roman period. Production from open cast quarries re started in the 11th Century. Shipped to England, Canterbury Cathedral, Westminster Abbey and the Tower of London were all partially built from Caen stone. Underground mining developed in the 19th Century, but the stone trade declined in the 20th Century stopping in the 1960s. Excavation restarted in the 1980s with the stone being used for building the Caen Memorial. A 2004 decree by Caen City council authorised the annual quarriyng of 9000 tonnes of stone.
- Caen stone was used in the construction of the late eleventh century austere Norman Romanesque Church of Saint-Étienne, at the Abbaye-aux-Hommes (on the east side of Caen), which was founded by William the Conqueror, whose tomb is located there.
- The Norman Romanesque Church of La Trinité, at the Abbaye-aux-Dames (on the west side of the city), was founded by William's wife, Matilda. Her tomb is located there.
- Both abbeys in Caen were built with Caen stone in Norman Romanesque style, and both were unscathed by heavy aerial bombing in July 1944 that destroyed much of the city, as they were being used by the local populace to shelter from the air raids.
- This stone was also a popular building material with the Normans in England. It was used in both the cathedral and castle at Norwich, where it was brought by boat up the River Wensum. Caen stone was also used extensively in Canterbury cathedral. It was used by Henry I of England at Reading Abbey and fine examples of Romanesque sculpture in Caen stone are in the collection at the Museum of Reading. Perhaps the most famous building in Caen stone built in Norman times is the Tower of London.
- Caen stone continued to be a popular material in Britain after the Norman period. For example, it was used for parts of the 19th century clock tower at the Palace of Westminster.
- Caen stone has also been exported to the USA, Bermuda and recently Saudi Arabia. The narthex screen on the east wall of the sanctuary at Old South Church in Boston, Massachusetts is built of Caen stone.
