From the 15th to 17th century, central Finistère had a period of unusual prosperity thanks to the trade of linen canvas.
As people from this area were quite devout, a large part of the money from the trade went to their clergy and to the building of enclos paroissiaux (parish closes). Each village of the area tried to rival its neighbours and build the finest parish possible, which yielded a series of calvaries, ossuaries and churches that look unusually large and ornate for small villages.
This phenomenon was particularly developped in a series of village South of a line joining Landerneau to Landivisiau. The photos of this section were taken in this area, called le Pays des enclos paroissiaux.
