Because of severe damage in the 1857 Fort Tejon earthquake , the Mission 's tile roof was replaced by a shingle roof . In 1893 , Cyprian Rubio " modernized " the interior of the church , painting over the original artwork ; when he finished , little of the old church was untouched . The windows were lengthened , the beamed ceiling and tile floor were covered , and the remnants of the quadrangle were razed . The west sacristy was removed to provide room for a school , which was not actually built until 1921 . During the pastorate of Patrick Grogan the roof of the church was once again tiled , the convent and present rectory were built , and a new fountain was placed in the garden
