Founded in 963 and expanded over the centuries, today the “Gibraltar of the North” is a UNESCO World Heritage site. The population used to hide in the tunnels during sieges. You can still tour them. Read more

Outside view is more beautiful than the view of inside. But must enter and walk inside the hundreds year old city caves .

Fascinating ! Definitely a must do while in Lux. Drop down into Gronn for beers afterwards.

Amazing! Definitely a lot of walking and stairs but the different levels and chambers where wonderful. The kids had the best time discovering different passageways and cannons.

A must-do historic attraction in Lux. Unbeatable 360 views of the city and a medieval atmosphere

Scenic and packed with history. Lots of stairs and watch your head.

Great #views worth spending a day up and down the historic site

Unbelievable stone tunnels and stairs in the millennium plus battlements, fairly priced admission too.

Great views of the city

Dogs allowed in (small to medium size) but you must carry them through turnstile at entry & exit!

Awesome site! Wear comfortable shoes good for walking/climbing MANY stairs .

Fantastic view , time-traveling feeling. Inspiration for nice photos .

Directions once inside aren't great. there's supposed to be an end-point with a turning circle but there isn't so you have to wait for everyone to turn around and come out single file... annoying

Offers nothing to see except for the views can get from outside as well and for free.

You can't possibly ask for more except for the great view !

Temporarily closed (went there in March 2023), check website beforehand.

Extremely interesting and keeping in perfect conditions parts of old city 's all.

Tunnels , lights, great atmosphere for pictures, getting lost....

Going down down down at I was my favorite part. You end up looking out the little windows in the bridge .

Must see if you visit Luxembourg! :)

Place to be in Lucembourg ;)

Histoire...............

Awesome Tunnels , Caves and Views of Old Luxembourg! Important: wear good shoes !

Patrimônio da Humanidade, bários andares de túneis escavados na rocha , para guardar alimentos , armas e proteger a cidade dos invasores, um dos maiores do continente

Im Jahre 963 baute Graf Sigfried auf dem Bockfelsen eine Burg , Grundstein der späteren Stadt Luxemburg. Mitte des 18. Jahrhunderts begannen die Österreicher mit dem Anlegen der Kasematten des Bockfels

Mi lugar favorito de la ciudad no se lo pierdan es muy interesante.

Modern bir şehrin hemen içinde, Ortaçağ mağaraları , nehir ve dağ manzarası çok güzel.

De las mejores vistas de la ciudad. Imprescindible para entender su gestación.

Precisa ser conhecido...no inverno possui uma charme especial

Не советую тратить время на осмотр этих подземелий, если наверху хорошая погода . Мрачно, сыро, неинформативно, вообще ничего интересного
