This is Europe’s Most Remote Construction Site — The B1M (2025)

Source: Original · Readwise highlight

It’s lodged into a rock summit called the Sphinx, positioned on a seriously sheer cliff face and terrifyingly, this gravity-defying building was actually constructed way back in 1937.

  • Role: subject
  • In the video: The B1M presenter stays overnight at the research lab built into the Sphinx rock summit at nearly 3,600 m. The video explains why it was built there (thin atmosphere for infrared measurements), that it was built in 1937 of steel and reinforced concrete, and how the 1990s Schindler lift shaft was cooled to protect permafrost.
  • Why it matters: It is the title subject, the ‘most remote construction site’ in Europe.
