In 1851 the original campus of Santa Clara College consisted of what remained of the Mission Santa Clara adobes built by the Franciscans. Newer wooden structures were built around the remaining adobe walls. As the campus was transformed by the Jesuit fathers, the campus buildings resembled less the Alta California Mission period and more the European traditions of the Italian immigrants and the American colleges of the time. In addition, fires, earthquakes and floods continued to transform the campus as they earlier shaped the original mission grounds.
