Construction work has started on the San Francisco City College building that will become the permanent home of Diego Rivera's monumental Pan American Unity mural.
The 74-feet-wide and 22-feet-tall work was created for an exhibition in the city in 1939 and two years later was installed in a theater lobby on the college campus where it stayed until 2021.
It is now in storage on campus and will stay there for two-and-a-half more years until the new building - the Diego Rivera Performing Arts Center - opens.
The building, designed by LMN architects and TEF Design, includes an open, glass-wrapped lobby that will showcase the mural.
Douglas Tom, from TEF Design, said the new building will give the mural "a prominent, accessible home where students, residents, and visitors can experience its significance firsthand".
