Groussbus-Wal, Luxembourg's newest commune

Groussbus-Wal is the youngest commune in Luxembourg. In February 2023 the Ministry of the Interior announced that Grosbous and Wahl, along with Bous and Waldbredimus, would merge on 1 September that year, leaving Luxembourg with exactly 100 communes, a number not seen since at least 1840, according to the announcement. The seat went to Grosbous. STATEC counted 2,390 residents on 1 January 2026.

The name causes some confusion. STATEC and the national register use Groussbus-Wal, the Luxembourgish spelling, while the commune’s website also uses Grosbous-Wahl. I go with the first because it’s the one in the official statistics, but expect to see both on signs.

Ten villages on the western plateau

The commune has ten localities and the council website lists the altitude of each. Grosbous, the main village, sits at 347 metres where the N12 meets the N21, and it’s mostly somewhere you pass through. Grevels climbs to 530, Heispelt to 503 and Lehrhof to 507. Wahl, the other half of the name, is at 459 alongside Redingshof, and the header photo shows its old town hall.

This is open, rolling farmland with whitewashed farmhouses like the one pictured in Grosbous. Don’t expect a historic centre or a high street. What’s worth your time is all in one spot.

Rindschleiden, the village with no residents

visitluxembourg calls Rindschleiden the smallest village in Luxembourg and adds that nobody lives there, at least no people, since at night there are only cats, pigs and hens. From the car park you can take in the whole place at a glance, the church, the museum, a bistro and a small park with apple trees. The commune’s website notes it was an independent commune up to 1823, and the tourist board says it was built on an old Celtic place of worship.

I like it precisely because there’s nothing else around. You park, and within an hour you’ve seen an exceptional church and walked through the woods. Coming from Britain, this is the sort of stop that justifies a hire car, since you’d struggle to build it into a day on public transport, and it pairs naturally with other villages in the west of the country.

The St Willibrord frescoes

St Willibrord’s church is the reason to make the trip. visitluxembourg explains that it began in the 10th century as a chapel of 5 by 10 metres and was enlarged several times from 1535, which is why the styles are mixed. Its 15th and 16th-century wall paintings cover more than 170 m² and weren’t rediscovered until 1952. Some scenes are damaged, but most are still legible, and they were painted so that people who couldn’t read could follow the Bible stories. It’s a national monument.

A grille set into the floor between nave and choir shows the foundations of the first chapel. Outside is St Willibrord’s spring, recorded as early as 1590, where on Whit Sunday the priests of Arsdorf, Buschrodt, Rambrouch, Rindschleiden and Wahl hold an open-air service. In the week of 29 September 2026 the church opened from 8:00 to 19:00, and in winter it closes at dusk, around 17:00.

Farm museum and meditation path

Next to the church is the Thillenvogtei, a living rural museum. visitluxembourg says groups can thresh wheat, dig potatoes, bake bread or sit at the desks of an old schoolroom, and individual entry is €5. If you turn up on your own, expect to see the building rather than the workshops.

Behind the church starts the Randschleider Pad, a 1.5 km meditation path with 12 stations that goes into a fir wood and comes back past a pond with the village beyond. For longer walks, the commune marks routes with each village’s initial (W for Wahl, G for Grevels, B for Buschrodt), and the Grosbous circular walk covers 8.55 km with 177 metres of climbing.

Fitting it into a trip

Groussbus-Wal belongs to Visit Guttland, one of its 27 communes, and lies east of Rambrouch, home to the Haut-Martelange slate museum. I’d combine the two in a morning’s drive. One odd detail to finish the loop, Turelbaach Castle, run by neighbouring Mertzig, actually stands on Grosbous land near Dellen. For the wider picture, see the guide to the Guttland.

So you do not lose the morning at the ticket office, browse tickets and tours in Diekirch on GetYourGuide.

Before you fix your dates, compare tickets to Luxembourg: the same journey can cost very different amounts from one day to the next.
