La Ventana de Rosa, the Rose Window, is located on the south wall of the church sacristy. The window has been described as the site where the Host was shown to gathered mission celebrants during the Feast of Pentecost.
The window, sculpted ca. 1775, has been the object of both legend and admiration. It is considered one of the finest examples of baroque architecture in North America. The meaning behind the name is currently unknown, but legend has it named for Rosa, the betrothed of Juan Huizar who many believe created the window.
