OSSINING – The Maryknoll Sisters in Ossining are counting their blessings after receiving hundreds of new windows for their nearly 100-year-old convent.

About 400 windows in the 92-year-old convent were more than six decades old.

They were impossible for the elderly sisters to open and close.  Sister Jeanne Houlihan says that in the winter, the building often felt like being trapped in the middle of a polar vortex.

Last July, the sisters went public about their desperate need for windows. Two months later, they raised $400,000 from 5,000 donors.

The Maryknoll nuns personally sent thank you letters to everyone who donated money for their new windows.

There are about 200 retired nuns living at the Maryknoll motherhouse.
