Known as the beacon light of Concordia, the well-known rose window looks over the community from the convent. It is the official Motherhouse and Home for the 260 Sisters of St. Joseph of Concordia. It was built in 1903 and is listed in the National Register of Historic Sites. The beautiful Lourdes-Park, restored in 1990, offers a place for walking and enjoying nature.

In 1884, the Rev. Joseph Perrier invited the Sisters of St. Joseph to come to Concordia to open a school in the Catholic Parish. Mother Stanislaus Leary, superior, and five sisters answered the invitation. They came to Concordia and established the Nazareth Motherhouse and Academy in a new building located next to the church.

The sisters quickly gained a fine reputation for the education of young women at Nazareth, giving them a sound academic program as well as instruction in the fine arts, music, French and the social graces. In 1903, the Sisters of St. Joseph entered the health care field in Concordia with the establishment of the St. Joseph Hospital on the original site after the new Nazareth Motherhouse was built at its present location.
