About Luxembourg City
Luxembourg City is one of Europe's wealthiest and smallest capitals, built into dramatic gorges where the Pétrusse and Alzette rivers have carved valleys. The old fortified upper town sits on spires and promontories, the Chemin de la Corniche walk reveals the extent of the defensive walls, and the museums document centuries of conquest and independence. It's expensive, orderly, and perfect for a concentrated day of sightseeing.

Luxembourg City is a compact capital perched on dramatic cliffs above the Alzette and Petrusse valleys, where centuries-old fortifications, the UNESCO-listed Bock Casemates and leafy parks sit alongside the glass towers of EU institutions and international banks. Its small size and trilingual culture make it an easy, walkable city break with a distinctly cosmopolitan feel.

Didn't expect such dramatic scenery in a capital city — the views from the Corniche over the valley and fortifications were stunning.

Free public transport made getting around really easy. The casemates tour was a fascinating, slightly eerie highlight.

Spent a weekend exploring Grund's riverside bars and the old town above. Compact enough to see a lot without feeling rushed.
