In the past year, audiences at the Cowell Theater in San Francisco’s Fort Mason Center have watched flamenco and ballet dancers, taken in musicals and plays, and attended the annual San Francisco International Arts Festival. What those attending may not have known is that until its reopening in August 2014, the more than 100-year-old pier structure housing the theater and exhibition space had been deteriorating from decades of exposure to a harsh marine environment. The recently completed rehabilitation, seismic repair, and energy efficiency upgrade have preserved Fort Mason Center as a cultural and community resource.
