Another freebee thing to do in Luxembourg City. Absolutely incredible building built into the rock of the city. 7/8 floors split across 2 buildings. Interesting mixture of national museum stuff, art and furniture. We really enjoyed it. Well worth a look

We visited mainly for the history related exhibits which are arranged below ground level. The deeper you go, the further back in history the exhibits take you. This is a very impressive building particularly because it is hewn out of the rock face. Highlight of the extensive Roman section is a well preserved mosaic floor featuring the muses believed to date from about 240 AD. On the lowest floors, bronze age dwellings take you back to 12,000 years BC. There is so much to see here it is possible to spend upwards of half a day. Everything is very well curated and presented. History exhibition is free, there are other art related areas where a ticket is required.

This is Luxembourg's main art and history museum. Right at the capital's historic downtown, it is a large place to understand the country from prehistory to contemporary development. More recent topics like household appliances and home design in the past decades are also covered. Visitors will have their own knowledge of the Luxembourgish way. Free admission except temporary exhibitons.

The mnha changed its name and is now called "mnaha" (musée national d'archéologie, histoire et art). Entry to permanent collection is free. You could spend days visiting the exceptional and very interesting collections. Check the museums website (English, French, German) and "prepare" your visit. My favorite to visit and revist is the mosaic of Vichten showing the 9 muses (daughters of Zeus). Take the elevator to -2, best spot for enjoying and taking a picture of the mosaic which was discovered in Lux./Vichten and restored to its old beauty. The informations are almost "French only", but you can still enjoy a great, memorable visit ... for free.
