The remains of the former Abbey of Notre-Dame de Clairefontaine are near Clairefontaine, a Belgian hamlet belonging to the city of Arlon. The valley has been inhabited since Roman times and castle Bardenbourg, in which amongst others Countess Ermesinde resided, saw several important personalities of its time. These included Pope Eugene III, who stopped there in 1147 with a group of 18 Cardinals on a trip from Rheims to Trier. The Pope's entourage included Bernard de Fontaine, who became a Saint. It was said that he had been told that someone in the lord of Bardenbourg's family was very ill. Thereupon he got water from a spring not far from the castle, and blessed the sick person with this water. The latter made a miraculous recovery, and this is said to be the origin of the name Clairefontaine. The water is still said to have healing properties.
About a hundred years later, Ermesinde had a vision, apparently seeing the Virgin Mary, and had the Cistercian abbey built here. As the Countess died in February 1247, it was her son Henry V the Blond who constructed the Abbey. It was first mentioned in records in 1250.
The Abbey was destroyed by French revolutionaries. This may be because the inhabitants of surrounding areas used the stones of the Abbey to build their houses.
Around 1875 the Jesuits of Arlon built a new chapel on the place of the old Abbey.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
