Bourscheid

Everyone in Luxembourg tells you to visit Vianden, and they are not wrong — it is a spectacular castle. But on the advice of the woman who ran our guesthouse, Lia and I drove instead to Bourscheid, twenty minutes south, and found ourselves more or less alone with the largest fortress in the entire Grand Duchy. It sits on a rocky spur some 150 metres above a tight loop of the River Sûre, and the approach by car winds up through dense forest until the towers suddenly appear above the trees, grey and broken-toothed against the sky.

A Thousand Years of Stone

There has been a fortification here since the tenth century, and the castle grew in fits and starts over the following six hundred years — a keep here, a defensive wall there, an entire lower bailey with the romantically named Stolzembourg house clinging to the outer ramparts. By the eighteenth century it had been abandoned, and for two hundred years it slowly crumbled, robbed of its stone by villagers who saw no reason to let good masonry go to waste. Restoration only began in earnest in the 1970s, and the result is honest: this is a ruin that has been stabilised and made walkable, not a fantasy rebuilt for the cameras.

I appreciated that. You climb the towers on modern steel staircases bolted into the old walls, and from the top the view is genuinely vertiginous — the Sûre coiling far below, the forested hills rolling away in every direction, and not a single tour bus in the car park. The audio guide, handed over with a wonderfully Luxembourgish lack of ceremony, tells the story through the voice of a fictional medieval inhabitant, and despite my general allergy to that sort of thing, it works.

The Valley Below

What stayed with me, though, was not the castle so much as the setting. We walked down afterward into the valley, following a marked trail that drops through beech woods to the river, and the contrast was total — from windy battlements to a hushed green corridor where the loudest sound was the Sûre sliding over its stones. Luxembourg is a small country that hides a surprising amount of wildness in its folds, and this stretch of the Ardennes is some of the best of it.

There is a tiny village clustered below the castle, the kind of place with one café and a church and not much else, and we sat outside with a coffee while a farmer drove a tractor past at a pace that suggested he had nowhere in particular to be. Lia declared it the most relaxed afternoon of the trip, which, given that the rest of the trip had hardly been frantic, is saying something.

When to go: April to October, when the castle is fully open and the forest trails are at their best. Autumn is especially fine, when the beech woods turn copper and the whole valley glows. Allow a couple of hours for the castle and the same again if you want to walk down to the river and back.
