Next weekend, the Los Angeles Museum of the Holocaust publicly opens the plate-glass doors of its brand-new home at the northwest corner of Pan Pacific Park for the first time. Observant visitors might be drawn to the building’s grass-covered roof, or the retro-futuristic shape of the windows, or the repeated use of triangles in a design that seems to nod to the six three-sided black pillars of the Los Angeles Holocaust Monument that sit just outside the museum.
