The Rosary Academy Learning Center was established in 1981 by the Saint Catharine Dominican Sisters who had founded and operated Rosary Academy on this site since 1911. Following the closing of the Academy in 1986, the decision was made to continue operation of the Learning Center because of the continuing demand in the Watertown area for quality preschool day care.
          In 1987, a major redevelopment of the Rosary Academy site was undertaken by the Dominican Sisters. The property is now Siena Village, an intergenerational community that includes a renovated school building that provides apartments for the elderly, a retirement center for the Sisters, facilities for the Ecumenical Life Center for Elders, renovated quarters for the Learning Center, and housing for families.
          Rosary is fully accredited by the National Academy of Early Childhood Programs, a division of the National Association for the Education of Young Children, (NAEYC).
