The foundations of "Notre Dame" were laid at the beginning of the 17th century as a Jesuit church in Gothic style. It was used under the statute of the cathedral from 1870 until Pope Pius XI consecrated the church to the Virgin. Later it was expanded and today the beautiful stained glass windows, the towers, the tomb of the Grand Dukes are of particular interest. The church was destroyed by a serious fire at the end of the 20th century, but was completely renovated in its original form. A monument to Grand Duchess Charlotte (1896 – 1985) stands in front of it.
