The massive pillars that support the façade, an architectural rarity, give the front of the building a somewhat cumbersome aspect that contrasts with the airy look of the high apse windows.

Another noteworthy detail of the building's exterior, testament to the troubled History of Jews in Alsace, is the presence of two "Judensäue", one in the shape of a gargoyle, the other as a corner sculpture of a portal.

[2] In the spacious interior, whose furniture had suffered bitter losses during the French Revolution, the most remarkable features are the exuberant Baroque organ case of 1755, (the mechanism and the pipes themselves, originally built by Johann Andreas Silbermann, were completely replaced in 1979), as well as the ambulatory, a unique feature in Alsatian churches.

Of the remaining Gothic stained glass windows in the nave, the most noteworthy is a 13th century head of a beardless Christ, another rare feature.

In 1462, the municipal painter Caspar Isenmann received a commission to paint a set of panels dedicated to the Life of Jesus Christ.
