Jean Baptiste Lamy brought architect Antoine Mouly and his son, Projectus Mouly, from Paris, France to Santa Fe to be architect - builders for what is now St. Francis Cathedral. It required ten years to build. During the first period of construction, and as an apparent afterthought, Archbishop Lamy advised and encouraged the sisters to utilize the father and son to design and build their dream chapel. The older Mouly had been involved in the renovation of Sainte Chapelle, in Paris, in the early 1800's. Mouly was encouraged to fashion the Loretto Chapel after the Sainte Chapelle. It was the favorite chapel of the archbishop from his early days in Paris, France. It is reported that the sisters pooled their own inheritances to raise the $30,000 required to build this beautiful Gothic chapel. It was decided that the school needed a chapel. Property was purchased and in 1873 work began on the Loretto Chapel.
