Founded in the XNUMXth century by Saint-Omer (Audomar) on the hill of Sithieu, the Notre-Dame chapel
quickly became an important place of pilgrimage. This chapel will then give way to a Romanesque church, then to the current Notre-Dame des miracles cathedral. Built between the XNUMXth and XNUMXth centuries, it displays all the currents of Gothic architecture (primitive, radiant, flamboyant).
Lovers of religious heritage will not fail to contemplate the richly decorated interior, the monumental nave, the treasures of sacred art and two breathtaking pieces of furniture: the organ case, built in the 1840th century, and the astronomical clock. Both are unique pieces testifying to an excellent know-how! It is not for nothing that the cathedral of Saint-Omer is recognized as one of the richest in France. It was classified on the first list of historical monuments in XNUMX.
In terms of dimensions, the Cathedral of Saint-Omer is 22,9 meters high under the vault, 105 meters long and 51 meters wide. Its tower measures 55 meters.
