Fort Point, San Francisco, CA is a national historical site well worth visiting. The circular stairwell leads to levels of preserved architectural history dating all the way back to the Civil War. The artistic movement of its beautiful brick masonry winds its way in curved-like motion down the stairwell while meeting its circular stairs. Old bricked arched passageways display impressive craftsmanship making this wonderful landmark an amazing worthwhile historical experience.
