Artwall, Public sculpture at Municipal Center Plaza, US.

Artwall is a 2005 outdoor sculpture by Herbert Dreiseitl along the east edge of Tanner Springs Park in Portland's Pearl District, at Northwest Marshall Street and Northwest 10th Avenue. The 17-by-200-foot work sets 368 weathered-steel reclaimed railroad tracks on end, separating the park's boardwalk from the meadow and wetland, with 99 fused-glass pieces inset with hand-painted images of amphibians, dragonflies, other insects and spiders.

Artwall was created in 2005 by German architect and artist Herbert Dreiseitl, who designed it together with Tanner Springs Park. It was funded by the City of Portland's Percent for Art program and by construction funds from the PDC. The work is part of the City of Portland and Multnomah County Public Art Collection, administered by the Regional Arts & Culture Council.

The wall's 99 fused-glass panels carry Dreiseitl's hand-painted images of amphibians, dragonflies, other insects and spiders, painted directly onto Portland glass before fusing. The 368 weathered-steel rails stand on end as reminders of the district's industrial past, separating the boardwalk from the meadow and wetland.

The wall runs along the east edge of Tanner Springs Park at Northwest Marshall Street and Northwest 10th Avenue, separating the boardwalk from the meadow and wetland. Walk the boardwalk side to see the glass insets up close; the 200-foot length is best taken in from a short distance.

The wall's 99 fused-glass panels carry images Dreiseitl hand-painted directly onto Portland glass before fusing; the Smithsonian Institution catalogues the work as both abstract and architectural, and the Regional Arts & Culture Council administers it as part of the City of Portland and Multnomah County Public Art Collection.
