Step beneath the surface into 1,800 meters of illuminated subterranean vaults, kinetic installations, and spatial acoustics.
Gallery Tunnelsy represents a physical synthesis of Seattle’s historical infrastructural utility and the avant-garde of contemporary environmental projection and sonic installation.
Carved originally into basalt layers in 1924, these heavy vaults served decades in absolute darkness. Today, they form a structured subterranean circuit specifically configured to isolate noise and block external light, creating an absolute baseline for artists to reconstruct space using light, shadow, and kinetic energy.
Thick earth dampens urban vibration, creating an uncompromised spatial sound design environment.
Zero light intrusion ensures exact colorimetric projection and high-fidelity optical illusions.
Interact with our architectural vaults below to discover key exhibits active in each subterranean quadrant.
A vaulted concrete space specially tuned for acoustic delay, currently staging "Echoes in Concrete" spatial audio. Every footstep integrates with physical synthesizers built within the architecture.
Learn MoreA 120-meter stretch illuminated by fiber-optic streams responding to underground air currents. Curated to study structural perspective through contrasting shadows.
Explore PathSurfaces framed entirely in raw hand-pressed clay tiles and suspended clay sculptures. This dry vault acts as a sensory baseline for earthen materials.
View SculpturePositioned 12 meters below Seattle's pavement, this cavern is dedicated strictly to silent kinetic projection maps. Features zero-frequency floor panels.
Architectural SpecsExperience three site-specific installations interacting with the heavy raw concrete structures.
"Tunnelsy redefines spatial art. The heavy concrete containment offers a rare acoustical and lighting playground you simply cannot achieve above ground."
