We will be climbing an internal stairwell at 555 California Street, San Francisco. We had our 2017 and 2018 climb events at this building and we really love working with them. They have been a huge supporter of the National First Responders Fund over the years. Formerly known as the Bank of America Center, 555 California is a 52-story 779 ft (237 m) skyscraper. It is the fourth tallest building in the City.
