Museums that pay off
Start at the MNHA (Musée National d’Histoire et d’Art) on Marché-aux-Poissons — 7 euros, closed Mondays. The Roman gallery with the Vichten mosaic and the medieval collection are the strong floors; give it two hours. Walk five minutes to the Lëtzebuerg City Museum on Rue du Saint-Esprit (5 euros) for the potted history of the fortress-city, useful context for everything else you’ll do.
Lunch nearby at Konrad Café or the covered market. Then take tram T1 from Hamilius to Philharmonie/MUDAM. Mudam (8 euros) is the country's contemporary art flagship — I.M. Pei building, strong temporary programme, and the glass atrium is a fine place to sit out a downpour with a coffee.
When the weather really doesn’t quit
The Bock Casemates are half-outdoor but the tunnels themselves are dry; 8 euros, two hours. Cinémathèque on Place du Théâtre shows arthouse and repertory films in original version (4 euros a seat, one of the cheapest tickets in the city). And the Cercle Cité often has free photo and architecture exhibitions on Place d’Armes.
For a fully indoor afternoon, La Coque on Kirchberg has a 50-metre swimming pool open to the public (10 euros) and Auchan Kirchberg is a full shopping centre if you’ve genuinely given up.

How often does it rain in Luxembourg?
The country averages around 200 rain days a year — expect drizzle on any given day October through March. It rarely pours for long; a rain layer and patience get you through most of it.
Are museums cheaper on any day?
MNHA and Villa Vauban are free on Thursdays after 18:00. Most municipal exhibitions at Cercle Cité are free always. The LuxembourgCard bundles most sites for 15 euros a day.
