The Chemin de la Corniche is a pedestrian promenade along the old ramparts on the eastern edge of Luxembourg City's upper town, running from the Bock promontory to the Holy Ghost Citadel. Below it, the Alzette valley drops away to the rooftops of the Grund and the Neumünster Abbey, with the Rham plateau on the far side. The view earned it a nickname attributed to the Luxembourg writer Batty Weber: 'the most beautiful balcony in Europe'.
Chemin de la Corniche at a glance
- Where: on the eastern edge of the upper town (Ville Haute), between the Bock promontory near the Montée de Clausen and the Holy Ghost Citadel (Plateau du Saint-Esprit).
- Built: the ramparts date from the 17th century, raised by the Spanish and then the French; the path took its present form after the fortress was dismantled from 1867.
- What it is today: a car-free walk on top of the old walls and part of the UNESCO World Heritage Site of the old quarters and fortifications of Luxembourg City.
- Time needed: 15–20 minutes for a slow walk end to end, longer if you stop at every viewpoint.
From fortress wall to promenade
For centuries Luxembourg was one of the strongest fortresses in Europe, and the rock above the Alzette was its eastern defence. The walls along the Corniche were built in the 17th century, first under Spanish rule and then by the French, who reinforced the whole fortress after taking the city in 1684. Back then this was a military rampart, not a promenade: the path was broken by flights of steps on its steep sections, and a protective wall with loopholes ran along the edge.
Everything changed after the Treaty of London of 1867, which made Luxembourg neutral and required the fortress to be dismantled. Over the following years much of the loopholed wall was removed and, by around 1870, the steps had been levelled into the gentle slope you walk on today. What had been a line of defence became a balcony over the valley. In 1994 the old quarters and fortifications of the city, including this stretch, were listed as a UNESCO World Heritage Site.
What to look for
- The Grund below: the old riverside quarter of narrow houses and slate roofs packed along the Alzette, directly beneath the wall.
- Neumünster Abbey: the large former abbey on the river, now a cultural centre, with the church of St John of the Grund beside it.
- The Rham plateau: on the far side of the valley, with the round towers and long walls of the outer fortifications.
- The Bock promontory: at the northern end of the walk, the rock where the city's first castle stood, riddled with the casemates tunnelled into it.
- The wall itself: look over the parapet at the height of the masonry built straight onto the cliff, and at the few surviving openings in the stone.
Why 'the most beautiful balcony'
The phrase 'the most beautiful balcony in Europe' is attributed to Batty Weber (1860–1940), a Luxembourg writer and journalist who for decades wrote a daily column about life in the city. Whether or not it is the most beautiful, the comparison makes sense on the spot: the Corniche is a narrow ledge high above an inhabited valley, with houses, gardens, church towers and the river laid out below like a stage set.
Tips for your visit
- Walk it in both directions if you have time: heading north, the Bock and the Rham towers stay in front of you; heading south, you look along the cliff towards the Holy Ghost Citadel.
- Late afternoon and early evening light falls on the Rham plateau and the Grund roofs opposite; after dark the old walls are lit.
- To reach the Grund without the climb back, use the public lift on the Plateau du Saint-Esprit, which connects the upper town with the valley.
- The cobbles can be slippery after rain, and the walk is popular at weekends, so keep to one side when you stop for photos.
Nearby
- Bock Casemates: the tunnels and galleries cut into the Bock rock, used as shelters and gun positions, a few minutes' walk from the northern end.
- Neumünster Abbey: down in the Grund, a former abbey and prison turned cultural centre with exhibitions, concerts and a riverside terrace.
- St Michael's Church: on the Fish Market, the oldest church site in the city, with a mix of Romanesque, Gothic and Baroque elements.
- Notre-Dame Cathedral: Luxembourg's cathedral with its slender spires, a short walk west across the upper town.
