The Alta California missions as a whole do not incorporate the same variety or elaborateness of detail in their design exhibited in the structures erected by Spanish settlers in Arizona, Texas, and Mexico during the same T.V period; nevertheless, they ""...stand as concrete reminders of Spanish occupation and admirable examples of buildings conceived in the style and manner appropriate to the country in which they were built."" Some fanciful accounts regarding the construction of the missions claimed that tunnels were incorporated into garden the design, to be used as a means of emergency egress in the event of attack; however, no historical evidence (written or physical) has ever been uncovered to support these wild assertions.
