In accordance with the wishes of her family, most of whom live in France, Saint Jani was buried in Baillou, a small village located in the region of Perche. On the initiative of her family and friends, and with the assistance of the AMSJ (Association du Mémorial de Sainte Janie), a memorial was erected in her memory. It was somewhat extraordinary for all the authorities, including the Town Hall of Baillou, the Sub-Prefecture of Vendôme, the Regional Department of Equipment and Facilities, and the "Communauté de communes des collines du Perche" to provide the authorizations necessary for the construction of this memorial, which is unique in France. According to the guidelines of the "Comité de la Charte des Espaces Naturels du Perche du Canton de Mondoubleau," dated May 16, 1994, given the exceptional nature of this memorial "it seems justified that a waiver to the general law that forbids any development outside of built-up areas should be granted," for the memorial contributes to "ennobling the site where it will be erected." Furthermore, "beyond the site itself, the quality of its style and materials are such that they can be considered an enrichment to the architectural heritage of Mondoubleau." Beyond these considerations, however, the memorial serves to remind us that everywhere in the world, there are men and women who are working whole-heartedly and selflessly to be a source of good for others. The memorial is an invitation to reflect for those who wish to follow their example and develop the same qualities within.

The construction of the memorial was a true challenge on several levels. First, it was an architectural challenge in that it required extensive research of lines and materials that combined simplicity and originality, solidity and fineness, within the limits of significant budgetary constraints. Second, it was a technical challenge in that the monument was a permanent prototype and thus had to be constructed and completed with exceptional precision. Finally, it was a challenge in that the work was performed by a team of paid workers and volunteers not only from different regions of France, but also from around the world. The cultural backgrounds of the workers were so diverse that at times none of them even spoke the same language. Indeed, constructing the memorial was a long and exacting task during which innovative techniques were used alongside ancestral ones such as the waterproofing of lead.

The pure and universal shapes of the memorial, cubes and pyramids, are a tribute to the person who inspired this monument. The base of the cube is a square measuring almost 14 meters in length on each side. Angled pillars are erected at each corner of the square, upon which four lintels rest, thus creating the upper lines. A four-sloped pyramid forms the roof. The monument was designed as a puzzle of 120 pieces, each weighing between one and ten tons and measuring up to eleven meters in length. All the elements had to be adjusted with extreme precision along three axes (height, length, and width). The monument was built with a clear, neutral reconstituted stone. The floor, the stairs and the forecourt, which has been designed to automatically drain water, were built with 3000 slabs of neutral reconstituted stone. Two stainless steel columns are inserted between each pillar; these supporting structures also moderate the contrast between the massive and archaic exterior of the memorial and its light and contemporary inner structure. An envelope made of glass, held and stretched by a ladder-like framework of stainless steel covered with tinted ash wood, appears to spring up from the ground to enhance the communion with the surrounding landscape with optimal transparency. The ceiling, as if suspended atop a pyramid, unwinds its four large sails in a spherical motion. Made from slats of ash wood, the ceiling was assembled with the use of shipbuilding techniques.

The harmony of the memorial is further enhanced by a design whereby hollow joints appear at regular intervals. The line formed by these joints is interrupted at times by the presence of golden elements. A pole 18 meters high extends the thrust of the pyramidal roof towards the sky. It is no coincidence that we are invited to look up and through this monument, for the luminous presence of Saint Jani and her memorial are an invitation to reflect upon another perspective on life.
