Mondorf JohnGrün

New monument John Grün

Built in November 2012 in honor of John Grün (1868-1912).
Mondorf-les-Bains boasted during the last years of the nineteenth century that he saw the birth of the strongest man in the world. His life would probably have passed peacefully in his hometown, in spite of his prodigious muscular strength, if the taste for adventure had not prompted the young adolescent to emigrate in 1889 to the United States, where he had a career and a notorious notoriety.


11 stones of memory were placed on November 6, 2015 by the artist Gunter Demnig in memory of the victims of Nazism, who lived in Mondorf-les-Bains and who were deported or executed during the Second World War.

Rue du Moulin, place Bernard Weber, Allée Jean Linster, rue John Grün, avenue Dr. Klein.

Birthplace of John Grün

23 John Grün Street, John Grün's birthplace. Still on foot today, it is part of the cultural and historical heritage of the Commune of Mondorf-les-Bains.

Former John Grün monument

This memorial was erected in 1920 by an organizing committee of 18 people and financed by public subscription.
From a sporting point of view, Grun is the first Luxembourger, before so many others, who has done honor to the foreigner to his little Luxembourg country and, as such, his memory deserves to be preserved. This is what this monument recalls.
Some of his equipment (weights and dumbbells, cast iron blocks, etc ...) is on display at the Sports Center Roll Delles in Mondorf-les-Bains.

Following numerous criticisms of the German Empire during the invasion of Luxembourg, he and two of his collaborators were arrested in mid-August 1914 and imprisoned for five weeks in a German prison. He later became a teacher and then resumed his position as editor-in-chief at the Tageblatt for a few years.

Altwies Castel

The Castel

A rocky spur crowned with a chapel, the Castel is located halfway between Mondorf and Altwies on the French shore of the Gander. Our Celtic ancestors, 25 centuries ago, already used the steep rock, difficult to access, as a refuge by barring its southern side by a tide of land, some tens of meters high, still visible today.

Maus Kätti Fountain

The artist Will Lofy, born in 1937, represented an episode of the work of Auguste Liesch (1874-1949) "Maus Ketti" recalling the fable of La Fontaine "the rat of the cities and the rat of the fields" . Sparkling staging of a visit that Ketti makes to his cousin Mim de Clausen. Let us not forget that the Luxembourg writer, born in Mondorf, regularly sent Ketti to take the waters to Mondorf after tight meals.
