This building, once owned by the Gas and Coke Gas Company was abandoned in 1957 and is a designated Superfund site. There is a security guard onsite at all times. Access to the interior is nearly impossible to come by for the general public, but this photographer was lucky enough to have the security guard give him a tour. The building in located on HWY 30 just outside of Portland on the way to Sauvie Island. I’ve always wondered what it looks like inside.
