The Huelen Zant (meaning "Hollow Tooth" in Luxembourgish) is a striking, partially destroyed stone tower located on the historic Bock promontory in Luxembourg City.
It is a highly romanticized remnant of the former Luxembourg Fortress, offering a dramatic vantage point with panoramic views of the Alzette River valley.
Declared a UNESCO World Heritage Site in 1994, this historical landmark is an ideal place to explore with your friends and family and is open twenty-four hours a day, all through the year.
