Time lapse: colossal Chernobyl shelter slides into place

Ukraine on Tuesday unveiled the world’s largest moveable metal structure over the Chernobyl nuclear power plant’s doomed fourth reactor to ensure the safety of Europeans for future generations.

The gigantic arch soars 108 metres (355 feet) into the sky – making it taller than New York’s Statue of Liberty – while its weight of 36,000 tonnes is three times heavier than the Eiffel Tower in Paris.
