You have just passed a tower which for a long time was considered to be a simple dovecote, or pigeon-house; this was in fact its function at the end of the 19th century.
Only recently has it become clear that this was indeed a clock tower. However, nothing is known about the time of its construction or how it operated!
Its dominant position and square shape might suggest that it was reused in the 17th or 18th century from an older building, such as a watchtower.
For the time being, the Mallemoisson clock tower remains a mystery, standing on a solid sandstone bedrock-base, the last witness to the presence of the sea in the Miocene period.
