Above the stove, Haartman has depicted Saint Bridget, the founder of the Bridgettine Order. The image is probably based on a medieval altarpiece. Saint Bridget can also be found in the center of the ceiling, where she is shown receiving a prophecy at her writing desk. The ceiling also features floor plans of the medieval Bridgettine monasteries of Vadstena and Nådendal.

On the ceiling, Axel has painted a rowan leaf with a bunch of rowan berries. This was an important symbol for Axel, as the cluster of rowan berries symbolized the couple's summer residence, Rönnudd, in Kimito. Rönnudd was built in the 1890s by Axel's mother, Hedvig. The cluster of rowan berries can also be found elsewhere in Casa Haartman. Sometimes, Axel used it in his signature when signing paintings.
