 The first feast in honour of the Crown of Thorns ("Festum susceptionis coronae Domini") was instituted at Paris in 1239, when Louis IX of France brought there the relic of the Crown of Thorns, which was deposited later in the Royal Chapel, erected in 1241–48 to guard this and other relics of the Passion.The feast, observed on 11 August, though at first special to the Royal Chapel, was gradually observed throughout the north of France.In the following century another festival of the Holy Crown on 4 May was instituted and was celebrated along with the Feast of the Invention of the Cross in parts of Spain, Germany, and Scandinavia.
