My mother, Leonia GOETKINT, spent most of her childhood at Hoogstraeten.  Pensionnat des Ursulines in Antwerp.  Does anyone know if they might have any of her records -  1925-1940?  All I know is it was a convent. 

On this page a number of postcards of exterior and interior of this boarding school/convent.
