Operation Typhoon: The German Drive on Moscow, 1941
In October 1941 two million Germans trapped half a million Soviet soldiers at Vyazma and pushed to within 30 km of the Kremlin. Mud, frost and a Siberian reserve stopped them.

Twenty kilometres from the Wolf's Lair, the German army built a hidden town of more than 200 structures. The Germans never blew it up, so the concrete is still there.

A camouflaged bunker town in the Masurian woods, where Hitler spent more than 800 days, survived a bomb on 20 July 1944 and was blown up by his own army as the Red Army closed in.

Founded in 1908 as a free hospital for poor Jewish patients, Zofiówka was emptied by the Germans on 19 August 1942 and has stood in ruins in the forests of Otwock ever since.

An earth dam with a concrete heart that survived the bouncing bombs in 1943, a Tallboy in 1944 and, in 1959, a live five-tonne bomb found at the bottom of its drained lake.

A Kaiser-era dam in the hills of Hesse, three villages beneath its lake and a gap blasted open in the early hours of 17 May 1943.

A Kaiser-era wall of quarry stone that held back the Ruhr's water for 30 years, was breached in minutes on 17 May 1943 and was closed again within four months.

Nineteen Lancasters, a bomb that bounced across the water and one night in May 1943: how 617 Squadron breached the Möhne and Eder dams, and what the raid really achieved.

A model Soviet city of about 49,000 people, emptied in a single afternoon in April 1986 and never resettled.

A safety test, a reactor with a fatal design flaw and a night shift that never had a chance: how Chernobyl happened, how it was hidden, and what it left behind.

A 150-metre steel wall in the Chernobyl Zone that tapped a mystery signal across the world's shortwave bands, and was never on a Soviet map.

Beside the abandoned city of Pripyat, about 100 kilometres north of Kyiv, the Chernobyl Nuclear Power Plant is still being decommissioned. Its story runs from the Soviet reactors that powered the region to the 1986 disaster, later accidents, and the 2022 invasion.

In February 1943, nine Norwegian saboteurs descended a frozen gorge, crept into the Vemork plant and destroyed its heavy water cells without firing a shot. Here is the full story of the raid, the escape to Sweden, and what really happened next.

Built in 1911 as the world's largest power station, Vemork later became the only industrial source of heavy water in occupied Europe. This guide follows its story from fertiliser works to wartime target to museum, with visiting details for today.
