The Vault of the Walloon Jesuits
The Jesuits were destined for Saint-Omer into 1566 by the bishop of Saint Omer, Gerard d' Haméricourt, to fight the Calvinism. A first vault was built into 1569. In 1614, after long negotiations with the aldermen of Saint-Omer, the Jesuits began the construction of one second vault street of the Net (current street of the College). Built out of brick and stone by the brother Of Blocq, this church includes/understands a nave, accompanied by two sides. The communication of these sides with the nave is done by six spans formed by flanked piles of two semi-columns of Doric order.
The building is still of design Gothic as attest it the two high towers of forty meters flanking the chorus, the twinge of the proportions (the vessel is higher and broader than that of Our-Lady), the luminosity of the interior, the use of ribbed vaults shouldered by arc-paring, the presence of a coursière on the level of the high windows. As for the frontage of the church, with its superposition of five stages rythmés by pilasters going from doric to the composite, its pediments and its rollings up in volutes, it is frankly of inspiration baroque.
The carcass work heavy castings were completed into 1626 and the frontage into 1629 as well as precise the date registered at the top of the pinion. The turns flanking the chorus were built between 1635 and 1640. Interior installations continued until 1640.
