About four kilometres southwest of Hattonchâtel, at the edge of the Woëvre plain, stand the partial remains of L'Étanche Abbey, a 12th-century Premonstratensian monastery. What survives is fragmentary — sections of wall, part of an arch, overgrown earthworks — but the setting in a hollow of meadow and woodland is evocative.
The site is not formally managed or signposted as a monument, which adds to its atmosphere: you find it by following farm tracks through the fields. It makes a good half-hour detour on a walk from the village down through the vineyards and onto the plain. Combine it with a circuit back up to Hattonchâtel via Saint-Maurice-sous-les-Côtes, a wine village whose Côtes de Meuse reds are worth tasting.
