Children from the Frederic Burk School enter the vaulted interior of Fort Point during a field trip to the Presidio and nearby cultural landmarks. Moving in a loose line beneath a series of arched openings, the students are dwarfed by the fort’s thick masonry walls and repetitive architectural forms. The photograph emphasizes the contrast between the scale of the nineteenth-century military structure and the small figures of the students, highlighting experiential learning through direct engagement with San Francisco’s historic sites.
