Faluns of Moulin Pochas in Amberre

This walk takes you through the Moulin Pochas falun site, which was used as a sandpit, and then continues with a short stroll across the plain through the fields. The site is not really a mill in the usual sense (such as a flour mill), but rather an ancient natural geological site consisting of falunières – quarries of ancient marine deposits (clay-sand cliffs known as faluns) – dating back some 15 million years. It is a unique testament in Poitou to the era when a shallow sea (the Mer des Faluns) covered the region. The site consists of ancient shell sand quarries containing marine fossils such as shells, corals, etc.

Description of the walk

On the D24 towards Vouzailles, look out for a ‘Parking’ sign on the right. Drive 100 m and park on the left in front of the old abandoned stadium.

(S/E) Leave the car park by turning left and heading towards Rigny to the north-west.

(1) Turn right at the edge of the woods, then left twice.

(2) Leave Rigny on your right and head straight across the fields for about 700 m.

(3) At the junction, take the track on the right, then the one on the left at the next junction, heading towards the Vallée d’Allet woods. Follow the edge of the woods until you reach a crossroads at the corner, a few dozen metres before a power line.

(4) Turn right, follow the edge of the woodland, then veer left to pass under the power line.

(5) Turn left, go straight on at the junction (elevation 108) and come out onto the D24.

(6) Cross it carefullyand continue straight ahead to reach the La Bruère junction.

(7) Take the road on the left and head towards La Miellerie.

(8) Turn left again, continue for about 200 m, then turn right towards Ambrette.

(9) At the hamlet, head to the right, turn right at the crossroads, then take the first path on the left.

(10) Take a path on the left. Just before you reach the D24, head down to the left to visit the old falunière. Take the underpass beneath the road, continue your visit, then return to the car park (S/E).

Notes

(S/E) In the car park there is an information board about the site, which was once used as a sand pit. The start of the walk is behind the board; unfortunately, the arrows and signs are all worn and therefore illegible, and the wooden steps are quite slippery in the morning. So please take care.

You can simply visit the site of the old flint quarry (about 1.5 km) without completing the circular loop.

Thank you for your feedback. It’s true that the route isn’t particularly remarkable, apart from the Falunière and its geological interest. It’s a shame that the information boards—which explained how these layers of sand were formed during the Falun Sea in theEocene, and the past and present use of the sandpit to improve agricultural fields or to make plaster for masonry, etc., etc.
