Istanbul – Luxembourg flights on monthly payments

When to visit Luxembourg

May to September is the easiest stretch, with daytime temperatures between 18C and 24C and the casemates and valley paths open. The Bock Casemates close in winter, so the choice of dates decides directly what can be visited. National Day at the end of June is the liveliest night of the year. November to February is cold, damp and short on daylight, though the Christmas markets fill the centre in December.

Things to do in Luxembourg

The Bock Casemates

The network of tunnels begun in the rock by the Spanish in 1644 and extended by Vauban's engineers and later the Austrians reached twenty three kilometres at its greatest extent. When the fortress was dismantled under the treaty of 1867, filling the tunnels in would have brought the city down, so this section was left as it was. The part open today shows gun embrasures and chambers cut into the stone.

Notre-Dame Cathedral

Built between 1613 and 1621 as a Jesuit church, the cathedral is an unusual case of late Gothic structure carrying Renaissance ornament, and the carving around its doorway is where that mixture shows most clearly. The crypt holds the tombs of the grand dukes of Luxembourg, its entrance guarded by two bronze lions. Three copper clad spires set the skyline.

The Grund and the Corniche walk

On the floor of the valley cut by the Alzette, the Grund is the oldest layer of settlement in the city, with its stone houses and water mills, joined to the upper town by lifts and stairways. The Chemin de la Corniche, the walkway along the top of the ramparts, looks down on it and was called the most beautiful balcony in Europe by the writer Batty Weber.

The Adolphe Bridge

The bridge across the Petrusse valley was built between 1900 and 1903 and on opening was the largest stone arch bridge in the world, with a span of 84 metres. It joins the two sides of the upper city and, taken as a symbol of independence, is still called the new bridge. The valley floor beneath it is laid out as a park, from which the bridge is seen at its full height.

The Grand Ducal Palace

Built in 1572 as the town hall, the building stands in a narrow street of the old town behind an ornamented Flemish Renaissance facade and has been the city residence of the grand duke since 1890. A guard is posted at its door and the changing of the guard can be watched. The interior opens only in summer, on guided tours with limited numbers.

Mudam Modern Art Museum

The museum on the Kirchberg plateau was designed by I. M. Pei and opened in 2006. The building sits on the surviving rampart foundations of Fort Thuengen, so a modern volume of glass and sandstone stands directly on the old fortification. The collection concentrates on contemporary art since 1990, and the glass domed entrance hall is worth the visit on its own.
