Or Maria Ward, pronounced in German to rhyme with “bard”
Yorkshire lass, born into a Catholic family at a time (16C) of great religious conflict in England, forcing her relocation to the continent where she entered a monastery in Saint Omer as a lay sister, later establishing the Congregation of Jesus and the Sisters of Lareto.
The statue is in the grounds of the Maria Ward school for young ladies on the Ballplatz.
Famous alumni being Lena from across the road and recently featured Karina

There’s something of a benevolent look to her.
I hope that the good sisters of that order are not as strict as some are, The statue makes Maria Ward look very severe. Not familiar with the Sisters of Lareto, but then there are as many religious orders for woman as there are stars in the sky or at least there used to be. “A school for young ladies” makes it sound a little ominous to me, an almost-graduate of an all-girls Catholic college prep high school. After two years my parents relented, and then I happily attended a local public school.
