In November 1843, congregation foundress
Saint Mother Theodore Guerin and
Sister Mary Cecilia Bailly were returning from France with three French
postulants after a fundraising trip. Sailing on the
Nashville, the
sisters encountered a fierce storm that threatened to sink the craft. The sisters prayed to the
Blessed Virgin Mary and to
St. Anne for safety. (Guerin originally hailed from
Brittany, France, where St. Anne is honored as patron of sailors.) Upon returning safely to Saint Mary-of-the-Woods, Guerin had a small log chapel built in honor of St. Anne on a small knoll in the forest of the
motherhouse grounds. This chapel was completed in 1844. After several decades, the logs in this structure began to give way. Under the leadership of General Superior
Mother Mary Ephrem Glenn, a sturdier stone chapel was built on the same site with the same 15' by 15' dimensions. This new chapel, called the
Shrine of St. Anne but more commonly known as the
Shell Chapel, was consecrated on July 25, 1876, with a blessing by a Father Chasse. Every July 25 since 1844, on the eve of the Feast of St. Anne, the sisters gather for a solemn procession to the chapel in honor of the saint. This procession includes songs and prayers. At its height, when nearly all Sisters of Providence spent the summers at Saint Mary-of-the-Woods, this procession may have included over 1,000 habited sisters. ==Interior and art==
