"The Sainte-Chapelle or 'Holy Chapel', in the courtyard of the royal palace on the Île de la Cité (now part of a later administrative complex known as La Conciergerie), was built to house Louis IX's collection of relics of Christ, which included the Crown of Thorns, the Image of Edessa and some thirty other items. Louis purchased his Passion relics from Baldwin II, the Latin emperor at Constantinople, for the sum of 135,000 livres, though this money was actually paid to the Venetians, to whom the relics had been pawned. The relics arrived in Paris in August 1239, carried from Venice by two Dominican friars. For the final stage of their journey they were carried by the King himself, barefoot and dressed as a penitent, a scene depicted in the Relics of the Passion window"
