The US Abandons Its Secret Ice City, Camp Century

The US Army shut down Camp Century, its secret nuclear-powered base carved into the Greenland ice sheet to conceal a mobile missile network under Project Iceworm, after the tunnels it depended on began collapsing.

Camp Century was a nuclear-powered US Army base under the Greenland ice sheet, built from 1959 (construction June 1959 to October 1960), with 21 tunnels totalling about 3 km, publicly a research and weather station^[2][3]
Per documents declassified in 1996 it was a preliminary camp for Project Iceworm, a plan for survivable nuclear missile launch sites (up to 600 modified Minuteman missiles); missiles were never fielded and Denmark never consented^[2][3]
The ice proved less stable than assessed: trenches compressed within four years, the reactor was shut down after over three years, and Iceworm was abandoned in 1963^[2][3]
The camp was abandoned after eight years of use, in 1966 per Task and Purpose and by 1967 per Wikipedia's operating dates^[2][3]
Hazardous waste, including radioactive waste, remains buried under the ice; ice cores supported climate science and Denmark's survey has monitored the site since 2017^[2][3]

Wikipedia states the camp "operated from 1959 until 1967," a one-year discrepancy with both the pin's stored 1966 date and the Task & Purpose account, reflecting some ambiguity in the exact closure year across sources.

Berlin Picks the Consortium to Bring the ICC Back
Internationales Congress Centrum, Charlottenburg, Berlin, Germany
开始于 2026/09/02已确认可信度 87%21天前Berlin's^[2][4] own press release fixes the day the decision landed: "Im laufenden Vergabeverfahren für das Internationale Congress Centrum (ICC) haben das Land Berlin und die als Bestbieterin hervorgegangene Projektpartnerschaft Quartier ICC heute, am 2. September 2026, eine Exklusivitätsvereinbarung unterzeichnet." That meets the city's hope of a decision before the end of 2026, so the year-end placeholder is replaced by the signing date; the ground-lease contract itself follows, with exclusivity running "bis zum 30. Juni 2027".
Berlin's abandoned, billion-mark ICC convention centre, nicknamed the 'spaceship', went out to tender for a 99-year ground lease, and the Land Berlin has now tied itself to one bidder: the Projektpartnerschaft Quartier ICC, which has until 30 June 2027 to negotiate the lease and a reuse plan built around events and the creative industries.
