€4.5 billion worth of gold bars has been returned to Poland after it was spirited from the country at the beginning of WW2.

Poland arranged an evacuation for all their gold reserves at the start of the war, this included 80 tonnes of gold bullion, banknotes and other assets.

The gold was split between three banks, Bank of Canada in Ottawa, the Federal Reserve Bank in New York and the Bank of England in London.

It took eight trips for 100 tonnes of gold to be transported to Narodowy Bank Polski.
