Скачать или смотреть North Korea Built Over These Tunnel Entrances — What Does It Suggest?

While reviewing historical satellite imagery in the Yongdok-tong region of North Korea, two tunnel entrances appear in the early 2000s that were not present in earlier imagery.

For several years, the entrances remain clearly visible from above. Later in the decade, a large structure is constructed directly over their location.

What makes this site stand out is not just the entrances themselves, but the broader development that follows. Between 2003 and 2023, the surrounding area evolves significantly — including expanded infrastructure, cultivated land, and larger residential structures compared to the immediate rural surroundings.

In other countries, underground facilities are sometimes enclosed or constructed over as part of hardened or protective site layouts. Viewers familiar with facilities such as the Cheyenne Mountain Complex may recognize comparable enclosure approaches used to protect underground access points.

Could a similar infrastructure approach be reflected here?

In this video, we step through the historical imagery year by year to examine:

• When the tunnel entrances first appear
• How long they remain exposed
• The construction of the overlying structure
• The broader site development between 2003 and 2023

Some open-source analyses have suggested the broader region may relate to high-explosive or nuclear testing support infrastructure. This video focuses strictly on observable changes in publicly available imagery and explores what those changes may suggest — without drawing definitive conclusions.
