About Bouillon

Bouillon is a dramatic medieval town in the deep Belgian Ardennes, nestled in a tight meander of the Semois River. Dominated by its magnificent medieval castle perched on a rocky spur, Bouillon was the ancestral home of Godfrey of Bouillon, leader of the First Crusade in 1096. Dense forest, falconry displays, and the haunting Semois valley make it one of Belgium's most romantic destinations.

Fascinating Bouillon Facts

  • Godfrey's Sacrifice: In 1095, Godfrey of Bouillon sold this very castle to fund the First Crusade — one of history's most consequential property transactions.
  • The Encyclopédie Connection: Voltaire's publisher printed Diderot's banned Encyclopédie in Bouillon in the 1770s, sheltered by the duchy's independent status.
  • First Crusade Leader: Godfrey refused to wear a crown as King of Jerusalem, saying he would not wear a crown of gold where Christ wore a crown of thorns. He took the title 'Defender of the Holy Sepulchre' instead.
