The Broad sits on Grand Avenue in Downtown Los Angeles, wrapped in a honeycomb shell of two thousand five hundred perforated concrete panels that its architects nicknamed "the veil." Underneath hides "the vault": a windowless mass holding most of the nearly two thousand artworks amassed by philanthropists Eli and Edythe Broad, visible to visitors gliding past on a glass walled escalator on their way to the galleries.

Opened in 2015 after years of wrangling over the tricky business of fabricating that perforated skin, the museum offers free general admission, a rarity for an institution stocked with Warhols, Koonses and one of Yayoi Kusama's mirrored infinity rooms. Its pale, porous curves make a deliberate foil for Frank Gehry's steel clad Walt Disney Concert Hall next door.

VoiceMap's self-guided audio tours pair The Broad with its Bunker Hill neighbours, tracing how Downtown's fortunes rose, collapsed and rebuilt around Grand Avenue's cultural cluster.
