Montagne de Bueren (French pronunciation: [mɔ̃taɲ də byʁɛn, -ʁən]) is a 374-step staircase in Liège, Belgium.

The staircase is named after Vincent de Bueren, who defended Liège against an attack by the Duke of Burgundy, Charles the Bold in the 15th century.

[3] In July 2020, in response to the impact of the COVID-19 pandemic in Belgium, Belgian explorer and adventurer Louis-Philippe Loncke ascended and descended the staircase 135 times carrying a 15 kg (33 lb) backpack, simulating an ascent of Mount Everest.

[4] The 9,000 m (30,000 ft) climb, which took 65 hours 30 minutes, was meant to show that one could still "find physical challenges close to home".

[4][5] On the night of 17 March 2024, it was repainted by Pro-Palestinian activists with the Palestinian flag.
