Artwall, also known as Art Wall,[1] is an outdoor 2005 sculpture by German architect and artist Herbert Dreiseitl, located at Tanner Springs Park in the Pearl District of Portland, Oregon.

[2][3] The art wall measures 17 feet (5.2 m) x 200 feet (61 m) and features 368 reclaimed railroad tracks (weathered steel)[1] standing on end and 99 pieces of fused glass inset with images of native wildlife such as amphibians, dragonflies, other insects, and spiders.

[3][4][5] Dreiseitl hand-painted the images directly onto Portland glass, before the pieces were fused and melted.

[3][4] The century-old tracks separate the park's boardwalk from the meadow and wetland portion, and have been described as "reminders of the area's industrial past".

In one urban block the skin of city is peeled back to reveal the landscape before its industrial development.
