Today the region houses numerous wind energy projects and is a tourist area with ancient cities like Clervaux, Prüm, Burg Reuland and Vianden.
The Codex Mariendalensis, a manuscript from the beginning of the 14th century, tells the story of Yolanda of Vianden.
•
The poem tells how Princess Yolanda gave up the comforts of her home in Vianden Castle to join the Convent of Marienthal where she later became the prioress.
Jackman cites Berthold of Ham (d. 1101), advocate of Prüm and documented with the Vianden cognomen, as a probable scion of this family and founder of the House of Vianden, a Sponheim branch.
The Vianden Pumped Storage Plant is located just north of Vianden in Diekirch District, Luxembourg.
Yolanda's lasting fame is due in large part to the epic poem Yolanda von Vianden (see more below), written by Friar Hermann of Veldenz, O.P., which is one of only two works we have from him, the other being a prose account of her life.
