Bock Casemates

"The Casemates du Bock, often referred to as simply the "Bock Casemates," are a historic underground network of tunnels and chambers in Luxembourg City. They offer excellent viewpoints overlooking the city and the Alzette River. You can walk along the fortified walls and enjoy vistas of the city's historic buildings, the Alzette River, and the surrounding valleys. In addition to the outdoor viewpoints, you can explore the extensive network of underground tunnels and chambers. These tunnels were once used for military purposes, and today they provide an interesting glimpse into Luxembourg's history."

"Tunnels under the city! They’re originally from hundreds of years ago but were also used during WW2. Normally you can tour them, but they’re going through renovations as of October 2022. "

"Entrance is regulated by timeslot, so if you book online make sure you respect the timeslot selected, alternatively you can walk in and buy tickets on site."
