I traveled to Luxembourg for one week in April 2015 to attend the yearly IHE European Connectathon. The workshop was a success like always, and it is always nice to meet old friends and colleagues there. But I actually want to talk more about the attractions I discovered.

Luxembourg City was impressive and very enjoyable. Everything was new and clean. People struck me as being quite nice too. The duchy is trilingual, speaking German, French and Luxembourgish. Many people can also speak English. It makes it easy for foreigners like me to adapt and find our way around the city.

The above are pictures from inside the city. It is quite picturesque, for that reason time is best spent taking the tram and getting off at each stop to wander around. The Luxembourg City History Museum is also well worth it; it relates the development of the city through topographical models and presents famous figures and objects. I would however not recommend the museum of Art which was a little disappointing. A great find was the city indoor swimming-pool, Badanstalt, that is actually closer to a high-end spa with very cheap prices and even has a solarium. If I lived there, I would go every week!

 A narrow valley divides the city in half. That lower ground, show on the pictures below, has a lot of greenery where one can exercise, and even an AWESOME open-air fitness center.

 I saved the most interesting area to visit for last, and that is the Bock casemates. They consist in a series of underground tunnels dug into the rock by the Spanish in 1644, then extended by the famous French fortifications engineer Vauban under Louis XIV during the 17th century, and much improved later by the Austrians during the 18th century, who made the casemates what they are now. The Bock casemates and surrounding fortified castle (mostly destroyed now) were among the best in the world and are the reason Luxembourg was left untouched and is still a duchy after being attacked by king-less France after the French Revolution. The tunnels were used as a bomb shelter during WWII.

The casemates can be visited for part of the year. Even during the off season, when they are closed, the views from the surrounding area are spectacular and well worth seeing.

To conclude, here is one of the most famous views of Luxembourg Old City taken from around the Bock casemates.
