Fort Thüngen

It is sited in Dräi Eechelen Park, in the Kirchberg quarter, in the north-east of the city.

It is also colloquially known as Three Acorns (Luxembourgish: Dräi Eechelen, French: Trois glands, German: Drei Eicheln) in reference to the acorns that sit atop each of the three towers.

[1] The fort was built in 1732-1733 and named after military commander Adam Sigmund von Thüngen [de].

[4] Most of the original fortress was demolished after the 1867 Treaty of London, which demanded the demolition of Luxembourg City's numerous fortifications.

After being fully restored, the building was reopened in 2012 as Musée Dräi Eechelen.
