Since the beginning of the 19th century, the Archaeological Society of Finistere (SAF) has set out to study and publicise the history and heritage of the department of Finistere. It has published an annual bulletin since 1873, and was acknowledged as an organisation of public benefit in 1889. To this day, the SAF remains one of the most important learned societies in France. It comprises about 1500 members of all ages and backgrounds. These include historians, art historians, archaeologists and scholars who deal with the publication of the bulletin, which is the principal activity of the Society. In addition, the society regularly publishes other works.
Last November 2010 the Archaeological Society of Finistere has published a book written by Louis Chauris: "Le Kersanton une pierre bretonne" (The Kersanton a Breton stone). The Kersanton - or kersantite - derives its name from the name of a village in the Bay of Brest in Brittany. This rock is easy to carve. It was used in many churches between the fifteenth and seventeenth centuries. Later, it was appreciated for the funerary art and after the World War I, for the erection of memorials. However, the largest volume of Kersanton, extracted in the second part of the nineteenth century and early twentieth century, was used in Housing and Public Works (port infrastructure, railways, lighthouses, ...).
Louis Chauris was born at Morlaix in 1930. He is a geologist and a research director at CNRS (retired).
The Archaeological Society of Finistere also proposes four trips from May to September. They are guided by experts who help understand the prehistoric monuments, the historical or religious sites, not only of Finistere, but also of neighboring counties.
