Shanghai tunnels, Underground tunnel network in Old Town Chinatown, Portland, United States
The Portland Underground consists of interconnected basements and passages stretching beneath the streets, linking former hotels and taverns to the Willamette River waterfront.
These tunnels, constructed during the 1800s, facilitated the transportation of goods from ships to basement storage areas, bypassing the congested streets of Portland.
The tunnels represent a complex part of Portland's maritime history, with stories of commerce, transportation, and alleged criminal activities in the nineteenth century.
Visitors can explore sections of the tunnels through guided tours starting at Old Town Pizza, which occupies the former Merchant Hotel building.
The underground network spans 14,000 square feet, with multiple trap doors still present in various Old Town establishments connecting to the tunnel system.
