The day after her visit to Prague crown princess Mary joined the other Danish royals for a remembrance service for empress Maria Feodorvna at Roskilde cathedral - the burial church of the Danish Royal House since the 14th century.
Mary's lady-in-waiting, Caroline Heering was also present (see video).
Mary wore a new hat by Susanne Juul.
Danish princess Dagmar married Russian tzar Alexander III. She took on the new Russian name of "Maria Feodorvna". The empress was buried in Denmark when she died in 1928. Because of the Revolution she had fled Russia years earlier. In 2006 her corpse was finally transferred to Russia to be buried with her husband and children - as she had wished for.
Mary was in the first stage of her pregnancy with Isabella. The news hadn't been made public yet.
