Ruines du château de Gannes

The ruins of Château de Gannes stand in the commune of L'Hôme-Chamondot, in the Orne department of Normandy. The remains lie roughly a kilometre northeast of the village centre, in the valley of the Jambée river near the La Motte farm, surrounded by a large pond that once formed part of the castle's natural defences.

How do you get there?

The ruins sit along a signposted walking trail that starts at the town hall car park in L'Hôme-Chamondot. The route passes through the village, goes by the church, then turns onto the second road on the right toward "La basse Métairie". From there a gravel farm track crosses open fields and loops around a small hedge-lined pond before joining the D617 road. After following the D617 for a short stretch, the path turns off again onto a sandy track that winds through heather and ferns straight to the castle ruins. Near the starting point, the Brasserie du Perche offers a convenient stop for a bite before or after the walk.

What will you see?

What survives of the fortress is mainly the base of a square keep measuring roughly 15 by 20 metres, raised on an artificial feudal mound (motte). Its walls, built from coarse flint rubble more than two metres thick, were reinforced at the corners with cut sandstone. The best-preserved section stands on the east side, where the masonry still rises to about ten metres — tall enough to give a real sense of the original structure's scale. The marshy valley and pond that surround the site explain why the castle was once considered nearly impregnable.

Château de Gannes was destroyed in 1428, during the Hundred Years' War, by English forces commanded by Thomas Montagu, Earl of Salisbury. Despite its strong defensive position on a mound protected by isolating marshland, English companies managed to storm and burn the fortress. Salisbury himself was killed shortly afterward at the siege of Orléans. The episode gave rise to a local legend of the White Lady: the castle lord's daughter, desperately in love with an English captain, is said to have betrayed her own people by opening the postern gate to the enemy.

The ruins were officially listed as a monument historique by decree on 11 October 1933, recognising their value as surviving evidence of medieval defensive architecture in the Perche region.

When should you visit?

The site is best visited during drier seasons — spring and summer — when the sandy and gravel sections of the trail are easiest to walk, since parts of the path can turn muddy after rain. Autumn brings its own appeal, as the heather and fern moorland around the ruins takes on rich seasonal colours. This is a destination for travellers looking for a quiet countryside walk paired with local history rather than a fully equipped tourist attraction, so sturdy footwear is recommended.
